Description
Technical field
The present invention relates to a kind of controller switching equipment technical field, particularly relate to a kind of isolating switch.
Background technology
Isolating switch, namely when dividing position, having the insulation distance of the requirement that conforms with the regulations and significantly disconnecting mark between contact, when co-bit is put, the switchgear of the electric current under the electric current under the normal loop condition of energy carrying and at the appointed time exceptional condition (such as short circuit), isolating switch (being commonly called as " disconnecting link "), generally refer to high voltage isolator, namely rated voltage is at 1kV and above isolating switch thereof, usually referred to as isolating switch, in high-voltage switch electric appliance, use maximum a kind of electrical equipment, the principles and structure of itself is fairly simple, but because use amount is large, functional reliability requires high, to electric substation, the design of power plant, the impact of foundation and safe operation is all larger, the main feature of isolating switch is without arc extinguishing ability, can only divide when there is no load current, close circuit, isolating switch is used for each step voltage, be used as to change circuit connect or make circuit or equipment and isolated from power, it does not stop ability, operate again after first circuit can only being disconnected with miscellaneous equipment, generally with the interlock of misoperation when preventing switch band load, sometimes pin is needed to prevent cut-off switch under the magneticaction of large fault.
Generally two each installations, one group of isolating switch before and after circuit breaker, object is all by circuit breaker and isolated from power, will form obvious cut-off point; Because what circuit breaker originally adopted is oil circuit breaker, oil circuit breaker needs often maintenance, therefore will there be obvious cut-off point two sides, is beneficial to maintenance; Generally, outgoing line cabinet is powered downwards from bus above by switch cubicle, before circuit breaker, need one group of isolating switch to be want and isolated from power, but sometimes, the possibility also having incoming call below of circuit breaker, as sent by the counter of other loop, the counter of the devices such as capacitor is sent, therefore circuit breaker below also need one group of isolating switch, isolating switch is mainly used for needing the part had a power failure reliably to isolate with live part, to ensure the safety of service work in high voltage distribution installation.
Current existing isolating switch complex structure, install inconvenient, structural stability is poor.
