Abstract
A kind of isolation cabinet handcart installing live locking element additional, it includes cabinet, and be located in cabinet relay control room, circuit breaker cart room, bus-bar room and cable vault, the isolation handcart homophase two ends in circuit breaker cart room install phase PT additional, and this PT secondary side causes electromagnetic lock.Using the present invention of technique scheme, install PT additional at isolation handcart homophase two ends, PT secondary side causes electromagnetic lock, so when there being electric locking handcart to operate, dead electricity unlocks, and the safety and reliability of work has been effectively ensured.
Description
Technical field
The present invention relates to high pressure equipment field, particularly a kind of isolation cabinet.
Background technology
On August 18th, 2016, Guiyang Power Supply Bureau occurs to overhaul teams and groups together in planning work 220kV Zha Zuo change cleaning 10kV
After I female end-of-job（Work director is handling work ticket termination formality）, maintainer processes 10kV segmentation without approval
During 0102 dolly disconnecting link cabinet bite defect, close 0102 disconnecting link by mistake, cause 10kV II master tape ground wire to close the pernicious maloperation of disconnecting link, short circuit
Arc light causes three people's flash burns, is tentatively judged as two grades of electric power person events.
In above-mentioned Guiyang Power Supply Bureau 8.18 event, staff carries ground wire to close isolation handcart, causes flash burn person thing
Part.Therefore, it is badly in need of a kind of safe and reliable device.
Content of the invention
It is an object of the invention to provide a kind of safe and reliable isolation cabinet handcart installing live locking element additional.
For achieving the above object, the present invention employs the following technical solutions：
A kind of isolation cabinet handcart installing live locking element additional, it includes cabinet, and the relay control room, disconnected being located in cabinet
Road device handcart room, bus-bar room and cable vault, the isolation handcart homophase two ends in circuit breaker cart room install phase PT additional, this PT bis-
Secondary side causes electromagnetic lock.
Described PT is located at cable vault.
Described bus-bar room is separated with circuit breaker cart room steel plate, and electromagnetic lock is located at the both sides of steel plate with PT.
Using the present invention of technique scheme, install PT additional at isolation handcart homophase two ends, PT secondary side causes electromagnetic lock,
So when there being electric locking handcart to operate, dead electricity unlocks, and the safety and reliability of work has been effectively ensured.
Brief description
Fig. 1 is the schematic diagram of isolation cabinet.
Fig. 2 isolates the sectional drawing of cabinet for the present invention.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of isolation cabinet handcart installing live locking element additional, it includes cabinet, and is located at cabinet
Interior relay control room 1, circuit breaker cart room 2, bus-bar room 3 and cable vault 4, the isolation handcart in circuit breaker cart room 2
Homophase two ends install phase PT additional, and this PT secondary side causes electromagnetic lock 5.
Described PT is located at cable vault.
Described bus-bar room is separated with circuit breaker cart room steel plate 6, and electromagnetic lock 5 is located at the both sides of steel plate with PT.
Install PT additional at isolation handcart homophase two ends, PT secondary side causes electromagnetic lock, so when there being electric locking handcart to operate, lose
Electrolysis lock.
If bus has ground wire on the downside of voltage, handcart not remove, PT has phase voltage, start electromagnetic lock locking handcart behaviour
Make.When downside ground wire is removed, PT one end is hanging, non-voltage or only drift voltage on PT, and electromagnetic lock dead electricity unlocks.
Because handcart is that three-phase operates simultaneously, earth lead or ground knife be also three-phase simultaneously, so cabinet only installs one
Phase PT.
