Description
Technical field
The utility model relates to a kind of electrical equipment, specifically a kind of vacuum isolating switch combined electrical apparatus with isolating switch, earthed switch and the stable performance together of vacuum circuit-breaker function combinations.
Background technology
The main effect of isolating switch (disconnecting link) is to isolate current/voltage when equipment or line maintenance, to guarantee safety.It can not disconnect load current and short circuit current, should be used with circuit breaker.Divide after when having a power failure, should dividing circuit breaker earlier and keep apart pass, splice grafting ground switch again.Divide earlier the ground connection switch when sending electricity, close circuit breaker after closing isolating switch.If misoperation will cause device damage and loss of life or personal injury.
Circuit breaker is used for closing and open circuit under the electric power system normal operation, automatically faulty equipment and circuit is disconnected under protective relaying device control during fault, and the automatic reclosing function can also be arranged.In China, what the use of the above transformer station of 10kV was more is air circuit and sulfur hexafluoride breaker.
Circuit breaker (or claiming switch) is the main electric control appliance of electric substation, has arc quenching characteristic, and when system normally moved, it can cut off and connect the zero load and the load current of circuit and various electric equipments; When system broke down, it and relaying protection cooperated, and energy is the disengagement failure electric current rapidly, to prevent expansion accident scope.Therefore, the quality of circuit breaker work directly has influence on the safe operation of electric power system.
Isolating switch is to use maximum a kind of electrical equipment in the high-voltage switch electric appliance, and the operation principle of itself and relatively simple for structure, but because use amount is big, functional reliability requires high is all bigger to the influence of design, foundation and the safe operation of electric substation, power plant.
Because the main distinction of circuit breaker and isolating switch is that circuit breaker has the ability of arc extinguishing, and isolating switch does not have.Thereby two kinds of equipment need be used, and its operating sequence is to close a floodgate: divide the ground connection switch earlier, close isolating switch, close circuit breaker then; Separating brake: divide circuit breaker earlier, the back is divided and is kept apart pass, splice grafting ground switch.
In the past, isolating switch and vacuum circuit-breaker branch were arranged, and in use, needed equipment many, complex structure, and it is big to take up room; And cost of investment height.Isolating switch and vacuum circuit-breaker combined electrical apparatus that isolating switch and vacuum circuit-breaker are combined have effectively been arranged at present, see Fig. 1, Fig. 1 is the structural representation of existing isolating switch and vacuum circuit-breaker combined electrical apparatus, wherein, isolating switch portion 21, vacuum circuit-breaker portion 22, grounding parts 23, operation locking part 24 and frame 25.Isolating switch portion 21 is arranged on a side of vacuum circuit-breaker portion 22; In isolating switch portion 21, be provided with and be used for the main contacts that is connected with vacuum circuit-breaker portion 22; Can manually close a floodgate and sub-switching operation by operation locking part 24.
But this combined electrical apparatus adopts magnetic switch to show closing of isolating switch part and disconnects, and when combined electrical apparatus is worked oscillation phenomenon can take place, and the magnetic switch unstable properties comes off easily, the wrong demonstration occur,
Cause the accident.And because travel control switch is not set, vacuum circuit-breaker portion separately when contacting stroke can not adjust, influenced result of use, can not satisfy the demand of electric power system.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this utility model provides a kind of vacuum isolating switch combined electrical apparatus, this combined electrical apparatus has been set up two auxiliary switches on original isolating switch and vacuum circuit-breaker combined electrical apparatus basis, make the combined electrical apparatus stable work in work, can satisfy the demand of electric power system.
The purpose of this utility model is achieved through the following technical solutions:
A kind of vacuum isolating switch combined electrical apparatus comprises isolating switch portion, vacuum circuit-breaker portion, grounding parts, operation locking part and frame, and isolating switch portion is arranged on a side of vacuum circuit-breaker portion; In isolating switch portion, be provided with and be used for the main contacts that is connected with vacuum circuit-breaker portion; Grounding parts is arranged on the opposite side of vacuum circuit-breaker portion; Isolating switch portion, vacuum circuit-breaker portion and grounding parts all are arranged in the frame; On frame, be provided with the operation locking part that is used for controlling isolating switch portion, vacuum circuit-breaker portion and grounding parts action; It is characterized in that: on frame, be provided with the travel switch that is used for showing the auxiliary switch of isolating switch part operating state and is used for adjusting vacuum circuit-breaker portion stroke.
In the utility model, auxiliary switch is arranged on the top of isolating switch portion, and auxiliary switch is connected with the relay indicating light of vacuum isolating switch combined electrical apparatus.Travel switch is arranged on the top of vacuum circuit-breaker portion, and travel switch is connected with motor, adjusts the vacuum circuit-breaker stroke by the stroke of control motor.
Compared with prior art, the utility model has been set up the auxiliary switch of a demonstration combined electrical apparatus operating state and the travel switch of an adjustment vacuum circuit-breaker portion stroke on original isolating switch and vacuum circuit-breaker combined electrical apparatus, make the combined electrical apparatus stable work in work, indication accurately, vacuum circuit-breaker portion stroke scalable has satisfied the demand of electric power system.
