Technical field
The utility model relates to power equipment, especially relates to a kind of low-voltage comprehensive compensation power distribution cabinet.
Background technology
At present, carry out along with the electric power system electrical network is intelligentized, existing switch cubicle, ammeter box and compensating cabinet all adopt mounting means separately, floor space is large, waste a large amount of man power and materials, the maintenance trouble can not satisfy each electric company to the requirement of intelligent power network
Summary of the invention
The purpose of this utility model be to provide a kind of can when the human electric shock, provide indirect contact protection, effectively compensating power, improve the quality of power supply, reduce the wastage, can provide the distribution service data, volume is little, lightweight, the low-voltage comprehensive compensation power distribution cabinet being convenient to install.
The purpose of this utility model is achieved in that
A kind of low-voltage comprehensive compensation power distribution cabinet, comprise cabinet, front cabinet door and rear cabinet door, feature is: be provided with front cabinet chamber and rear cabinet chamber in cabinet, middle diaphragm plate is divided into top measuring room and following compensated chamber with front cabinet chamber, three-phase four-wire system electric energy meter and concentrator are installed in measuring room, intelligent reactive power controller, miniature circuit breaker, combination switch, capacitor, temperature controller, signal lamp and fan are installed in the compensated chamber; Rear cabinet chamber is the switch gear room, and knife switch, earth leakage protective device, current transformer and lightning arrester are installed in the switch gear room.
The utility model organically gathers together compensated chamber and existing measuring room and switch gear room.In the compensated chamber, gather current signal by intelligent reactive power controller first, the current signal that collects is through combination switch, combination switch arranges the current range that a palpus gathers according to client's needs, when bus current excursion (being that power factor does not reach electric company's requirement) combination switch not in the scope that intelligent reactive power controller is set closes, drop into capacitor, when the power factor of user power utilization reaches electric company's requirement (in the scope that intelligent reactive power controller is set), combination switch disconnects, capacitor excises automatically, so just can make the reactive power consumption of electrical network remain on minimum state, thereby improve the utilance of the quality of power supply and equipment.
The utlity model has the function of electric leakage, overload protection, lightning protection and reactive power compensation; it can greatly reduce because of device damage and the personal safety accident of being struck by lightning and electric leakage causes; when power system frequency and voltage drop, improve simultaneously power factor, guarantee the quality of power supply.Therefore; the utlity model has can when the human electric shock, provide indirect contact protection, effectively compensating power, improve the quality of power supply, reduce the wastage, can provide the distribution service data, volume is little, lightweight, the advantage being convenient to install, is to integrate protection, metering, measurement, compensation, communication, the modernized novel product of thunder-lightning.
