Load control switching device of emergency power supply vehicle

Abstract

The invention discloses a load control switching device of an emergency power supply vehicle. The load control switching device solves the problem that when an existing generator set outputs electric energy, a control switch does not exist. The load control switching device is characterized by comprising a switching cabinet, an electric leakage breaker, three current mutual inductors, an electric energy meter, an incoming wire cable and an outgoing wire cable. The incoming wire cable is connected with an incoming wire cable wiring terminal on the upper portion of the electric leakage breaker through the current mutual inductors, the outgoing wire cable is connected with an outgoing wire cable wiring terminal on the lower portion of the electric leakage breaker, and the current mutual inductors are further connected with the electric energy meter. The load control switching device is movable, when not used, the load control switching device can be stored in the power supply vehicle, cut-in or quit of loads of a client terminal can be effectively controlled according to the site conditions, the phenomenon that when an electric generator is cold and parts are not fully lubricated, the parts run with loads is avoided, the electric leakage breaker has the electric leakage short-circuit protection function, when the client terminal is in short circuit or in ground connection, the electric leakage breaker conducts rapid breaking in the first time, the service life of the generator set is prolonged, and in the electric generation, the electric energy meter can provide the real and accurate electric energy data.

Description

technical field

[0001] The present invention relates to a control device of an emergency power supply vehicle, more precisely, relates to a device for controlling the load of an emergency power supply vehicle by the emergency power supply vehicle. Background technique

[0002] When a general emergency power supply vehicle provides emergency power supply to customers, the generator set has no control switch when outputting electric energy, and can only rely on the customer's control switch to control the disconnection and cut-in of the load. It is inconvenient and unsafe to use, but the generator set is safe. The protection function is not perfect enough. Moreover, since the emergency power supply vehicle does not have a switch to control the outflow of electric energy, according to the operating regulations of the generator set, the generator must be unloaded for 3-5 minutes before being connected to the load; Insufficient lubrication of the parts may easily cause the gener...
