Even the most cutting-edge and high-tech heating technology can not be self-sufficient. Availability of control sensors, automatic control, fans and units for exhaust and injection air mass makes the heating boiler is dependent on electricity. These features are not spared and solid units, which many used to take completely independent heating devices. Any malfunction of the power supply system is extremely negative impact not only on the efficiency of the heating system, but also can cause the boiler equipment failure. This is especially frustrating in the dead of winter, when the greatest load falls to the autonomous heating system.
Solve the problem of constant power heating units will bespereboynik for solid fuel boilers - device, which is equipped today almost every household equipped with various appliances destination.
What is a UPS? The main technical requirements for the device
UPS stands for - an uninterruptible power supply, in English UPS. The device is designed to provide for a certain period of time of any power supply apparatus, device or mechanism for normal operation. Bespereboynik is a kind of safeguard against unauthorized disconnections centralized power supply, which can lead to failure of energy-dependent equipment and the loss of his functionality.
Uninterruptible power supply device is equipped with almost any modern technology, which in one way or another, structurally related to electricity. In each case, the equipment for autonomous electricity used their type bespereboynik having certain parameters and specific characteristics.
For instance: UPS for office equipment has a certain capacity and output voltage, whereas for bespereboynik household domestic appliances, including heaters, designed for other electrical options. In this case, the device has structural features.
Let's start from the beginning. What distinguishes bespereboynik power for Boilers, Boiler, from similar devices, standing on other electrical equipment.
1. Uninterruptible power supply for heating units must have the parameters of output voltage identical to the parameters of electrical equipment, which costs on equipment solid fuel boilers. Sinusoidal voltage waveform characteristic of the solenoid valves, provides operation of pumps and blowers. Only in this case, the disappearance of the current network, electrical appliances, the heating unit will operate normally.
Important! Use to operate the boiler UPS designed for computer equipment is not recommended. The reason is that such devices do not provide a sinusoidal voltage, on the contrary, give the office bespereboynik rectangular square wave with zero.
2. The apparatus for uninterruptible power heating units for solid fuels must provide a sufficiently long-term operation of the heating equipment. In other words, the battery capacity must be large, which would provide autonomous operation of boiler equipment during the absence of power supply. Cleaning device designed for a maximum power of 10-15 minutes, calculated only for the fact that the computer equipment to derive from the operation mode without fail.
3. Any boiler, solid devices are no exception, are sensitive to voltage surges. When the bespereboynik must receive enough power from the battery sufficient to ensure that would generate a voltage of the same phase as in the centralized network.
4. At faults in the network and trips, transfer coal-fired boiler for power supply from the UPS should not exceed 10 milliseconds.
Types bespereboynik for solid-fuel heating appliances
Any autonomous heating system is equipped with bespereboynik. Depending on the species and type of boiler equipment, installed an uninterrupted power supply of the appropriate type. To date, in practical uses three types of UPS:
- off-line apparatus;
- ; Interactive - Line devices
- dual converters, On-line system.
Each device model is distinguished by its design and function. Let us consider in more detail.
Bespereboynik off-line are the most common devices. They have a simple design and affordable price. At the core of the work based on the following principle:
- the disappearance of the mains voltage, voltage drops sets in motion a chain UPS - battery. Appeared voltage returns the unit to normal mode - the mains. Time switching device for power supply from the battery and vice versa, is not more than 15 milliseconds.
The product consists of traditional elements: an inverter that converts the direct current to the battery in the electric voltage of 220V. Models such as off-line work from the power supply voltage 170-270V. The main difference of this type is that they do not have a voltage regulator, so the output voltage in such bespereboynik equivalent voltage.
On a note: If unstable power supply, bespereboynik constantly switched on the battery, the power supply to a centralized network. This regime leads to a rapid reduction in product life.
Another type of UPS used in practice, interactive uninterruptible power supply. These devices are equipment that occupies the middle niche, both in functionality and in terms of cost. The principle of operation of interactive source of autonomous power inverters is similar to the off-line. The only difference is the presence of the voltage regulator. Due to its design, such devices more reliable and safe in operation. Each model in this case is designed to interact with the central power supply network 170-270V.
Last, the third type bespereboynik is a device operating in a live-time, on-line. In these devices virtually no disadvantages of the two other types of UPS. The main highlight of these devices are as follows:
- UPS in real time converts input alternating current into a constant voltage, regardless of its parameters and characteristics. Subsequently transformation occurs already in the stabilized DC, AC voltage.
These models have a huge advantage to the same UPS on-line to effectively work in tandem with generator sets. This feature is very relevant in situations where there is no centralized power supply a long time, the work of electrical appliances depends on the functionality of the autonomous mini power stations.
From a technological point of view, the UPS design on-line is quite complicated. Accordingly, the high cost of such products. The usefulness of such equipment is justified under the circumstances, when installed boiler models that are sensitive to power surges.
Based on the foregoing, it is possible to draw certain conclusions. Most often, for the normal operation of boilers, coal-fired, wood and other kinds of solid fuelEnough to get active bespereboynik device or off-line. When a country house or in the private sector due to the frequent power cuts primary load falls on diesel generators, the best option would be the purchase of an uninterruptible power supply on-line.
Bespereboynik choice. What to look for
The choice bespereboynik for solid fuel boilers affects a variety of factors. First of all, you must determine the capacity of the heating unit, the functionality of the heating system that will provide in the event of a UPS needed.
Largely on the capacity of the boiler it depends not only on the type of uninterruptible power supply, but also the type of battery. Battery capacity is determined by the duration of the work bespereboynik. The table shows the parameters of the equipment according to one or the other heaters.
| The boiler output, W |
50 | 100 | 150 | 200 | 300 | 400 | 500 |
| Battery capacity (battery) Am / h | |||||||
| 65 | 6.8 | 6.8 | 3.9 | 2.2 | 1.5 | 1.1 | 0.7 |
| 100 | 25.7 | 12.2 | 7.2 | 5.4 | 3.1 | 1.8 | 1.4 |
| 150 | 37.9 | 18.1 | 12.1 | 8.1 | 5.4 | 3.4 | 2.1 |
| 250 | 49.2 | 24.6 | 16.0 | 12.0 | 7.3 | 5.5 | 3.8 |
To choose the type of UPS is influenced not only by the power of the heating system, but the number of additional units working on electricity. This should include fans, pumps, heating systems, monitoring devices, alarm and adjustment.
Optimum UPS choice also depends on the quality of centralized power supply, which include frequency of trips, duration of outages and voltage fluctuations in the range of the network.
Important! In the analysis of the UPS capacity do not forget about the induction load. Mechanisms and appliances, standing on equipping heating appliances provide significant inductive load on the internal grid. When running fans or circulators load on the network increases in 3-6 times. Current models bespereboynik can withstand short-term overload, however, the best option would be buying a UPS with a power reserve of 25-30%.
conclusion
Ultimately, when you buy the device should pay attention to its autonomy. The duration of the UPS depends on the battery capacity. Accordingly, the larger battery capacity, the higher the cost of the device. Typically, the UPS in the auxiliary heating system uses two types of stationary batteries: AGM or GEL. This device, made on the basis of lead-acid cells.
GEL type batteries have a higher capacity and are designed for heavy loads. In addition, this type of battery has a significant resource charge and discharge cycles.
On a note: for solid fuel boilers (any heating appliances) should not use car batteries. The reason is the chemical composition of the oxidant. Using the UPS to operate auxiliary boiler involves the installation device together with the battery in the boiler room. Evaporation of hydrogen during operation of the heating equipment can eventually lead to the formation of explosive hydrogen-oxygen mixture.
Proposed types of batteries for bespereboynik have a huge advantage - they do not need constant maintenance.
