Description
Technical field
The utility model relates to a kind of fixed switch cubicle, the isolating switch in the specifically fixed switch cubicle and the interlock of circuit breaker.
Background technology
Because the isolating switch at the lead-in circuit breaker two ends of fixed switch cubicle is to be contained on two cabinets, two isolating switches use two fully independently operating mechanism controls.In case mistake appears in operation sequence, just might produce high-voltage arc, produce high-voltage arc after, equipment must be burnt out, and the blast that produces of high-voltage arc also can be gone out the cabinet door-plate and hurts operating personnel.For the fail safe that guarantees to operate, improve operating personnel's safety, need between isolating switch and circuit breaker interlock be set, restriction operating personnel operation sequence is in accordance with regulations operated, reduce the probability that misoperation takes place, farthest guarantee operating personnel's personal safety.Yet the structure of present interlock is comparatively complicated, and trouble is installed, and the interlocking effect is reliable and stable inadequately.
Summary of the invention
The technical problems to be solved in the utility model provides the isolating switch in a kind of fixed switch cubicle and the interlock of circuit breaker, this device is easy to operate, guarantee that isolating switch and circuit breaker operation sequence according to the rules carries out deciliter, guarantee operating personnel's personal safety.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
The isolating switch in a kind of fixed switch cubicle and the interlock of circuit breaker, comprise isolating switch cabinet, isolator operation handle and breaker cabinet, breaker operator handle, isolating switch is equiped with the isolating switch cutterhead cashier's office in a shop, be equiped with the circuit breaker cutterhead on the breaker cabinet, the regulating rod that also comprises the handle hole phase clamping on an end and the clamping mutually of isolating switch handle hole cashier's office in a shop, the other end and the breaker cabinet, and one end be loaded on isolating switch cashier's office in a shop, the other end is loaded on the synchronizing bar on the breaker cabinet, these synchronizing bar two ends activity respectively are equiped with the gear handle.
The front side of described isolating switch cabinet cutterhead and circuit breaker cutterhead all offers longitudinal fluting.
The utility model is by establishing regulating rod and synchronizing bar between isolating switch cabinet in fixed switch cubicle and breaker cabinet, assurance isolating switch and circuit breaker operation sequence are according to the rules operated, the high-voltage arc of avoiding misoperation to bring, guarantee operating personnel's safety, make the more safe and reliable operation of equipment.

Embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the isolating switch in a kind of fixed switch cubicle and the interlock of circuit breaker, comprise isolating switch cabinet 1, isolator operation handle 2 and breaker cabinet 3, breaker operator handle 4, be equiped with isolating switch cutterhead 5 on the isolating switch cabinet 1, be equiped with circuit breaker cutterhead 6 on the breaker cabinet 3, also comprise the handle hole clamping mutually on an end and the isolating switch cabinet 1, handle hole on the other end and the breaker cabinet 3 is the regulating rod 7 of clamping mutually, and one end be loaded on the isolating switch cabinet 1, the other end is loaded on the synchronizing bar 8 on the breaker cabinet 3, and these synchronizing bar 8 two ends activity respectively are equiped with gear handle 9.For regulating rod 7 is better slided, the front side of isolating switch cabinet cutterhead 5 and circuit breaker cutterhead 6 all offers longitudinal fluting.Synchronizing bar guarantees that the gear handle moves simultaneously, makes two gear handles move to the maintenance shelves simultaneously, guarantees operating personnel's safety.
Below with send electricity and when having a power failure the course of action of each parts of the utility model be that example specifies; need to prove; the following stated is the specific descriptions to technical solutions of the utility model; be not to be qualification to the present utility model content; under the prerequisite that does not break away from inventive concept of the present utility model, any conspicuous replacement is all within protection range of the present utility model.
As shown in Figure 1, the gear handle all is transferred to the maintenance shelves, and this moment, isolating switch cabinet and breaker cabinet all were in gate-dividing state, and primary element in the fixed switch cubicle and electrified body are all kept apart not charged, and the door-plate that can open switch cubicle overhauls, and is safe and reliable.
When fixed switch cubicle send electricity, as shown in Figure 2, at first closed the cabinet door of fixed switch cubicle, the gear handle is transferred to the operation gear, because the effect of synchronizing bar, the gear handle of being located at the synchronizing bar two ends is transferred to the operation gear simultaneously, one end of regulating rod puts in the handle hole on the breaker cabinet cutterhead, and the breaker operator handle can't be operated owing to be subjected to stopping of regulating rod, and the disconnecting link of breaker cabinet can't close, can only close the disconnecting link of isolating switch cabinet, the disconnecting link of isolating switch cabinet is closed.Because the front side of isolating switch cabinet and breaker cabinet offers groove, regulating rod can slide between isolating switch cabinet and breaker cabinet, in the handle hole on the breaker operator handle insertion circuit breaker cutterhead, regulating rod one end is subjected to the extruding of breaker operator handle, makes the regulating rod other end extend into the handle hole that the interior also shelves of isolating switch handle hole are cashier's office in a shop lived this isolating switch cabinet.In the time of disconnecting link on the breaker cabinet need being closed, need earlier the gear handle at synchronizing bar two ends to be transferred to the work shelves simultaneously, behind the disconnecting link on the breaker cabinet that closes, as shown in Figure 3, send electric program to finish.At this moment, regulating rod one end puts in the handle hole of isolating switch cabinet, and the gear handle at synchronizing bar two ends all is in the work gear.
During power failure, as shown in Figure 4, the gear handle is transferred to the operation shelves, divide circuit breaker disconnecting link cashier's office in a shop earlier, live this handle hole owing to regulating rod one end extend into isolating switch handle hole home record cashier's office in a shop this moment, the isolating switch cabinet operating grip can't be operated, and isolating switch disconnecting link cashier's office in a shop can't disjunction, avoids the charged disjunction of disconnecting link of isolating switch cabinet.As shown in Figure 5, separately behind the disconnecting link on the circuit breaker isolating switch cabinet operating grip is inserted in the handle hole of isolating switch cabinet, the end that regulating rod is contacted with breaker cabinet extend in the handle hole of breaker cabinet, separate isolating switch disconnecting link cashier's office in a shop this moment, the gear handle is transferred to the maintenance gear, and as shown in Figure 1, the cabinet door-plate that can open fixed switch cubicle overhauls, switch cubicle charging operation not when having guaranteed maintenance has guaranteed operating personnel's safety.
