Description
Technical field
The utility model belongs to technical field of electric equipment, more particularly to a kind of low-voltage compensating device.
Background technology
Inductance electric discharge supplement energy when hindering electric current flowing is made by the charge and discharge electro ultrafiltration of electric capacity in alternating current circuit, works as electricity
Feel due to the energy that electric capacity charging absorption inductor is produced when electric current reduces generation electromotive force.It is of virtually the electrical equipment of inductive nature
It is a lot.Compensate general power (apparent energy is the power seen into), active power (power played a role), the nothing of meaning
Work(power (power not played a role), and general power=active power+reactive power of circuit.It is on reactive power theory
Electric energy is not consumed, it can increase general power in terms of formula.If taking indemnifying measure, that can just add it is standby, and not
Loop excess load can be made.It is nervous in China's supply of electric power, reactive power is substantially reduced with indemnifying measure, it is meant that has more
People can have access to electricity simultaneously, the section of power failure can be reduced.It is existing compensation equipment defect be, the theoretical radius of electricity supply of circuit
Greatly, the voltage level of load side is reduced.
The content of the invention
There is provided a kind of low-voltage compensating device for shortcoming of the prior art for the utility model.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
A kind of low-voltage compensating device, including protection module and anti-interference module, the anti-interference module include two and resisted
Interference module, described two immunity modules are parallel with one another, and the immunity module includes A.C. contactor and capacitor, described
A.C. contactor and capacitor series connection, the protection module include switch and lightning rod, the switch and lightning rod series connection
And lightning rod is grounded, the switch series connection anti-interference module.
As a kind of embodiment, also include electric capacity in the immunity module, the electric capacity is connected on the exchange
Between contactor and capacitor.
It is used as a kind of embodiment, the model CDC9-25A of the A.C. contactor.
It is used as a kind of embodiment, the model BSMJ0.323-4-1 of the capacitor.
The utility model is as a result of above technical scheme, with significant technique effect：
The utility model energy lifting system low-voltage standard up to standard, it is ensured that reliability and extend other electricity that household electrical appliance are used
The service life of gas equipment；Transformer utilization factor is greatly improved, transformer iron loss, copper loss, line loss is reduced.It is provided with excessively stream guarantor
Shield, overvoltage protection makes voltage compensating device safe and reliable to operation, power network and user's electrical equipment is exempted from the broken of low-voltage
It is bad；Powered instruction is provided with, branch road input is indicated, load full voltage, compensation branch current are shown and protection act reason is indicated.
