Risk, for example, bus protection regular inspection, fault wave recording device transformation etc., this kind of safety measure work early period arrangement needs to own
The current loop at interval is reliably shorted, and current terminal, which is commonly shorted method, to be had：1, test wire is shorted, and uses more test wires pair
Current loop is shorted, and the benefit of this method is can be shorted to non-conterminous terminal, and flexibly and easily, disadvantage is to be shorted
It is asynchronous in the process, negative phase-sequence or zero-sequence current may be generated in current loop, influence power system stability operation；2, metal is short
Contact pin will directly be shorted piece and be placed on the terminal that needs are shorted and be screwed, and easy to operate, multiphase current is able to achieve together
Step is shorted, and disadvantage is that the terminal to be shorted must be adjacent, cannot be bridged, and itself is all-metal, and touching is easy when use
Electricity；3, short connector mainly increases the handle that can insulate on the basis of metal connecting sheet, and screw will be needed to fix originally
It has been changed to plug-in, it is both convenient and efficient, electric shock risk is also prevented, the disadvantage is that the terminal being shorted must be terminals of adjacent,
It cannot bridge.The above common current terminal is shorted method the advantages of having oneself and disadvantage, cannot reach wanting of being reliably shorted
It asks, carrys out systematic risk to plant maintenance work belt, therefore design and a adjustable conveniently reach reliable short
The short connector of purpose is connect, the work risk in power production process can be reduced, improves working efficiency, guarantees electricity net safety stable fortune
Row.
In power production process, current loop open circuit will generate very high potential on secondary coil, threaten person peace
Entirely, the damage of instrument, protective device, secondary insulating is caused, especially working on the current loop not having a power failure, it is very big to have
Risk, for example, bus protection regular inspection, fault wave recording device transformation etc..
Current terminal, which is commonly shorted method, to be had：
1, test wire is shorted, and is shorted using more test wires to current loop, the benefit of this method is can be right
Non-conterminous terminal is shorted, flexibly and easily, disadvantage be it is asynchronous during being easy accidentally to touch electricity and being shorted, may be in electric current
Negative phase-sequence or zero-sequence current are generated in circuit, influence power system stability operation；
2, metal is shorted piece, will directly be shorted piece and be placed on the terminal that needs are shorted and be screwed, advantage uses
Extensively, multiphase current is able to achieve synchronous short circuit, and disadvantage is that the terminal to be shorted must be adjacent, cannot bridge, and itself
For all-metal, when use, is easy to happen electric shock, inconvenient；
3, short connector mainly increases the handle that can insulate on the basis of metal connecting sheet, and will need spiral shell originally
Silk fixation has been changed to plug-in, and advantage is convenient and efficient, it is therefore prevented that electric shock risk, the disadvantage is that the terminal being shorted must be abutting end
Son can not bridge；
The above common current terminal is shorted method the advantages of having oneself and disadvantage, is not able to satisfy in a variety of situations reliable
The requirement of short circuit carrys out systematic risk to plant maintenance work belt.
