Description
Technical field
The present invention relates to high voltage isolator technical field, and field is excluded more particularly, to disconnecting switch heating accident.
Background technology
In generating, power transmission and transformation, with the high-tension distribution equipment device for power utilization network system, disconnecting switch is for need to
Have a power failure the capital equipment that part reliably isolates with live part, and disconnecting switch has obvious isolation cut-off point after pulling open, with
Ensure the security reliability of site maintenance operations work.Because disconnecting switch does not have an arc-control device, contact junction block is all open
In atmosphere, it therefore can not be used for cutting off load current or short circuit current, otherwise under high pressure effect, will be produced in cut-off point strong
Strong electric arc, and be difficult self-extinguish, or even arc short-circuit is caused, scaling loss equipment, jeopardize personal safety.Disconnecting switch can be with
For carrying out the handover operation of some circuits, to change hair, defeated, change, the distribution network system method of operation.Such as：In design configurations
In the power supply of double-bus circuit, operating power supply can be run from I female switch on mother II with disconnecting switch, while can also use
To operate the circuit of some low currents, such as voltage transformer, arrester, zero load bus, the zero load transformer of low capacity,
Unloaded or Smaller load circuit.
Annual season summer and autumn high fever wet season, most transmission lines of electricity, disconnecting switch, bus are in high energy operation shape
State, cause disconnecting switch junction block because of oxidation, loose contact, load energy is excessive and seriously generates heat.Wherein, when high energy high current exists
In opposing seal, the less junction block in space on the soft copper piece of curling by when, the caused eddy current effect on curling soft copper piece
Under the double action of high voltage kelvin effect, necessarily cause the serious heating of junction block.For the above situation, existing solution party
Case includes two kinds of integral replacing and detachable maintaining part, such scheme could power-on time is longer, and economic loss is huge stopping,
Solves the halfway problem of heating problem.

Further, the quantity of the drainage wire is 2, and the every drainage wire includes two bursts of soft copper silks, often
The area of section of the stock soft copper silk is 50mm2。
Further, the drainage wire is fixedly connected by device clamp with the outlet board.
Further, it is described drainage wire along its length be shaped as arc.
The present invention on the outside of existing disconnecting switch junction block by setting drainage wire, and the drainage wire is led with inside
Line forms parallel connectivity, makes to be diverted to drainage wire by a part for the electric current of junction block inner lead, in junction block
The electric current of portion's wire is accordingly reduced so that junction block caused by high current in curling soft copper piece on caused eddy current effect and
High voltage kelvin effect accordingly weakens, and then reduces the caloric value of junction block, ensures that caloric value is run in safe range.On
State design and both do not need integral replacing disconnecting switch, it is not required that junction block integral demounting gets off to repair part again, province of saving trouble
Shi Shengqian, thoroughly solves heating and service life is grown.
The drainage wire connects anchor ear by line nose, connects outlet board by device clamp, makes the two of drainage wire
End is connected firmly, convenient disassembly.Conducting rod is socketed by anchor ear, makes contact close, fax is passed more securely and reliably, is not likely to produce
Electric arc or spark.Two bursts of soft copper silks built in every drainage wire use, add the section of drainage wire, further improve water conservancy diversion
Ability.
