Abstract
The utility model discloses a movable temporary DC screen and relates to the technical field of power maintenance devices, which comprises a DC ammeter, a DC voltmeter, an insulation monitor and a voltage monitor. The DC ammeter is connected in series with the bus of the positive electrode of a power supply. The DC voltmeter, the insulation monitor and the voltage monitor are connected in parallel between the buses of the positive electrode and the negative electrode of the power supply. More than two sets of DC output wiring terminals are led out from the buses of the positive electrode and the negative electrode of the power supply. During the modification of a DC screen in a power substation, the DC power load is poured out by means of the movable temporary DC screen, so as to ensure the power supply of a DC system. Meanwhile, the movable temporary DC screen is provided with enough DC output wiring terminals and is impeccable in insulation monitoring and voltage monitoring function. During operation, the movable temporary DC screen can alarm in time in case of DC ground faults or voltage abnormal faults, so that people can handle the faults in time. Thus, the movable temporary DC screen is higher in both security and reliability.
Description
Technical field
The utility model relates to electric power maintenance device technique field, relates in particular to the interim direct current cabinet of a kind of movable type.
Background technology
When electricity substation is transformed at direct current, need utilize interim direct current transition screen that dc load is poured out, original interim direct current transition screen is simpler and cruder; Insufficiency; If there is not alarm signal when in the direct current retrofit work, causing ground connection or electric voltage exception, and the direct current output wiring terminal is less, and multichannel goes out specific electric load and is crimped on the direct current output wiring terminal; Operating and working together is that inconvenience is dangerous again, is easy to cause direct current dead electricity and short circuit.
The utility model content
The utility model technical problem to be solved provides the interim direct current cabinet of a kind of movable type, has perfect insulating monitoring and voltage monitor function, and fail safe and reliability are higher.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: the interim direct current cabinet of a kind of movable type; It is characterized in that comprising DC ammeter, D.C. voltmeter, insulating monitoring device and voltage monitor; Said DC ammeter is connected on the cathode power supply bus, and said D.C. voltmeter, insulating monitoring device and voltage monitor are connected in parallel between anodal and the negative power supply bus, draws two groups of above direct current output wiring terminals on cathode power supply bus and the negative power supply bus.
The further scheme of the utility model is: 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 has 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, and fail safe and reliability are higher.
