The further scheme of the utility model is: said battery feed car comprises a plurality of storage batterys, D.C. voltmeter and ventilating fan; Said battery feed car is a double-layer structure up and down; A plurality of storage battery series connection are placed in the casing of dolly; Power output end at said battery feed car is parallel with D.C. voltmeter, and said ventilating fan is fixed on outside the casing of dolly.
The interim direct current cabinet of said movable type comprises DC ammeter, D.C. voltmeter, insulating monitoring device and voltage monitor; Said DC ammeter is connected on the cathode power supply bus; Said D.C. voltmeter, insulating monitoring device and voltage monitor are connected in parallel between anodal and the negative power supply bus, draw two groups of above direct current output wiring terminals on cathode power supply bus and the negative power supply bus.
The interim direct current cabinet of said movable type also comprises flasher, and power source bus is that flasher provides power supply, and the flash of light bus is that flasher provides flashing light.
Said cathode power supply bus, negative power supply bus and flash of light bus are drawn direct current output wiring terminal more than two groups through switch respectively.
Be provided with power supply indicator between cathode power supply bus and the negative power supply bus in every group of direct current output wiring terminal, the closure of switch can be controlled the light on and off of power supply indicator on the out-put supply bus.
Said switch is the direct current air circuit breaker.
Adopt the beneficial effect that technique scheme produced to be: the direct current cabinet in the electricity substation is when transforming; Can utilize the interim direct current cabinet of said movable type; Dc load is poured out, guarantee the direct current system power supply, and the interim direct current cabinet of said movable type is had abundant direct current output wiring terminal; Perfect insulating monitoring and voltage monitor function can in time be reported to the police and handle it in its work if when causing DC earthing or electric voltage exception.Electricity substation is when carrying out the storage battery transformation and change, and the battery feed car replaces former batteries operation, prevent the loop break down, load increase suddenly, charger breaking when charger itself breaks down, cause the direct current dead electricity.When emergency or direct current system paralysis appear in the direct current system in the electricity substation; Substitute former direct current system operation with said system emergency; Shortened the time interval that during troubleshooting dc load can not normal power supply; Reduced the probability of expansion, improved the stability and the reliability of electric power netting safe running because the direct current dead electricity causes the accident.
