At present, become, the low pressure of power distribution station becomes, low-pressure line-outgoing cabinet in distribution system is all traditional low pressure place line cabinet.This low-pressure line-outgoing cabinet comprises low-voltage cable and cabinet, and described low-voltage cable is the threephase cable be made up of A phase, B phase, C phase and zero line N.A phase, the B phase of low-voltage cable, between C phase end of incoming cables and leading-out terminal, all there is circuit breaker summation current transformer.Described cabinet there is multi-functional manipulating device, described multi-functional manipulating dress.Be connected with circuit breaker summation current transformer respectively by wire, gathered voltage signal and the current signal of low-voltage cable by multi-functional manipulating device by circuit breaker summation current transformer.Due to low-voltage cable A phase, B phase, between C phase end of incoming cables and leading-out terminal, circuit breaker summation current transformer is only installed, only rely on the tripping operation of circuit breaker to avoid the electrical fire accident caused by short circuit and overload.There is trip action definite value due to this method and the deficiency such as the time affects greatly by environmental change, poor reliability, be difficult to play preventing electric fire effectively act on, the generation of appliance fire accident cannot be avoided.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of two yuan and changes low-pressure line-outgoing control cubicle.Adopt this two yuan of colored low-pressure line-outgoing control cubicles, can play preventing electric fire and effectively act on, reduce the generation of electrical fire accident.
The problems referred to above that the present invention will solve are realized by following technical scheme:
Two yuan of change low-pressure line-outgoing control cubicles of the present invention comprise low-voltage cable and cabinet, and described low-voltage cable is the threephase cable be made up of A phase, B phase, C phase and zero line N.Circuit breaker summation current transformer is had successively between the end of incoming cables of low-voltage cable and leading-out terminal.Described cabinet has multi-functional manipulating device, described multi-functional manipulating device respectively with circuit breaker summation current transformer and be connected, is gathered voltage signal and the current signal of low-voltage cable by wire by circuit breaker summation current transformer by multi-functional manipulating device.Be characterized in there is fire detector between described current transformer and leading-out terminal.
Wherein, described circuit breaker is frame circuit breaker.
Auxiliary switch, switching winding, closing coil, energy storage motor and energy storage auxiliary switch is had in described circuit breaker, the auxiliary switch of leading up to of multi-functional manipulating device is connected with the zero line N of low-voltage cable with switching winding, auxiliary switch of leading up to is connected with the zero line N of low-voltage cable with closing coil, and described energy storage motor of leading up in addition is connected with the zero line N of low-voltage cable with energy storage auxiliary switch.
Take such scheme, have the following advantages:
As can be seen from the above scheme, owing to being connected to current transformer and fire detector at leading-out terminal, can relevant real-time electric parameter accurately in rapid detection system and loop and residual current, and accurately estimate, extract the information of electrical fire, scientificlly and effectively prevent the generation of electrical fire accident.Thus achieve electric wiring to low-pressure line-outgoing control cubicle, prediction, the identification of electrical fire that electric equipment, electric elements may cause because of faults such as short circuit, overload, three-phase imbalance, ground connection, prevent and protect.
