Description
Technical field
The utility model relates to the high-voltage electrical equipment technical field, relates to a kind of structure that circuit breaker is joined the interlock of switch cubicle that is used for.
Background technology
Present domestic 12kV stationary cabinet is based on the XGN2 switch cubicle, the 12kV circuit breaker is based on VS1, two kinds of main products are combined becomes a kind of trend, yet how to realize " five is anti-" requirement of this combination product, different solutions is arranged, the requirement that but present method is many can not well to solve " five prevent " is at realizing that how reliable, effective realize " five prevent " requires this problem to propose patent of the present invention.
The utility model content
The purpose of this utility model is to provide a kind of can solve the interlock that circuit breaker is joined the problem of switch cubicle " five is anti-" interlocking, realized requirement highly reliable, simple in structure.
For achieving the above object, the utility model provides a kind of interlock that circuit breaker is joined switch cubicle that is used for, it is characterized in that: comprise the joint that is connected with the operating grip of mechanical locking device, the interlocking guide rod that is connected with joint, the interlocking shaft that is connected with chain guide rod, chain of the circuit breaker that is connected with interlocking shaft, and return unit, winning in succession in chain of wherein said circuit breaker and the switch cubicle is connected.
Preferably, described joint is connected with described interlocking guide rod through threaded, and described joint and chain guide rod move up and down according to the operation of the operating grip of mechanical locking device.
Preferably, described chain guide rod is vertical with interlocking shaft to be provided with, and it connects by brace, and described interlocking shaft rotates by moving up and down of chain guide rod.
Preferably, described return unit is a torsion spring, and the one end is fixed on the described interlocking shaft, and its other end can be fixed on the rack inwall.
Preferably, this interlock also comprises mounting angle plate and the axle sleeve that is fixed in the switch cubicle, and described interlocking shaft is connected on the described mounting angle plate by axle sleeve.
The utility model adopts the original interlock of VS1 handcart type breaker, the branch of circuit breaker, the state that closes is delivered on the lock operation dish of XGN2 type switch cubicle by blocking lever, thereby realizes the requirement that the breaker closing state can not disconnecting switch operation; Position with the lock operation dish is delivered on the circuit breaker by blocking lever simultaneously, thereby realizes the lock operation dish can not close circuit breaker at the disjunction locked position of coupler requirement.
The characteristics of the utility model patent also are simple in structure, by part seldom, just can realize requirement.Realize simultaneously that by set of parts circuit breaker can not disconnecting switch operation and the switch cubicle requirement that can not close circuit breaker at the disjunction locked position of coupler at closing position.
Description of drawings
Fig. 1 is the structural representation that meets interlock of the present utility model;
Fig. 2 is the interlocking principle schematic of interlock shown in Figure 1.
Among the figure, the 1-joint; The 2-guide rod of interlocking; The 3-interlocking shaft; The 4-torsion spring; The 5-mounting angle plate; The 6-axle sleeve; Chain of 7-circuit breaker; The 8-brace; The 9-mechanical locking device; 10-wins in succession; The 11-connecting rod; 12-combined floodgate semiaxis; 13-circuit breaker interlocking shaft.
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment
Please refer to Fig. 1 and Fig. 2, meet and of the present utility modelly the utility model is elaborated below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1, interlock comprises the joint 1 that is connected with the operating grip of mechanical locking device 9, the interlocking guide rod 2 that is connected with joint 1, the interlocking shaft 3 that is connected with chain guide rod 2, chain 7 of the circuit breaker that is connected with interlocking shaft 3, and return unit 4, and winning in succession in chain 7 of wherein said circuit breaker and the switch cubicle 10 is connected.Wherein said joint 1 and described interlocking guide rod 2 are by being threaded, and described joint 1 moves up and down with the operation of chain guide rod 2 according to the operating grip of mechanical locking device 9.Described chain guide rod 2 and interlocking shaft 3 vertical settings, and by brace 8 connections, described interlocking shaft 3 rotates by moving up and down of chain guide rod 2.Described return unit is a torsion spring 4, and the one end is fixed on the described interlocking shaft 3, and its other end can be fixed on the rack inwall.This interlock also comprises mounting angle plate 5 and the axle sleeve 6 that is fixed in the switch cubicle, and described interlocking shaft 3 is connected on the described mounting angle plate 5 by axle sleeve 6.
Please refer to Fig. 1 and Fig. 2, when operation XGN2 switch cubicle mechanical locking device 9 is rotated clockwise to the disjunction locked position of coupler by the service position, mechanical locking device 9 promotes interlocking shaft 3 by joint 1, interlocking guide rod 2 and rotates, the rotation of interlocking shaft 3 promotes circuit breaker locking plate 7 and moves upward, circuit breaker locking plate 7 promotes to win in succession and 10 moves upward, with 12 lockings of breaker closing semiaxis, prevent that the circuit breaker circuit breaker from closing a floodgate by connecting rod 11 when the disjunction locked position of coupler.Simultaneously if circuit breaker is in closing position (circuit breaker interlocking shaft 13 is in the A position), circuit breaker interlocking shaft 13 will be pushed down and win 10 in succession, making wins in succession 10 can't move, be rigidly connected owing to be connected to, mechanical locking device 9 just can't clockwise rotate (being that mechanical locking device can't forward the disjunction locked position of coupler from the service position to) disconnecting switch operation in the time of can preventing breaker closing like this.
Adopt interlock described in the utility model can realize that switch cubicle " five anti-" requires promptly: to prevent the on-load branch, close isolating switch (breaker closing state can not disconnecting switch operation); Close when preventing that earthed switch is in the close position and close circuit breaker (have only when earthed switch to be in gate-dividing state, just can close isolating switch, could operating breaker closure); Prevent at charged mistiming splice grafting ground switch (only at the breaker open operation state, could disconnecting switch operation, earthed switch just can close); Prevent mistakenly entering charged chamber (only be in the branch state, just can open door of switch cabinet) at upper and lower isolating switch; Prevent that mistake from closing mistake and dividing circuit breaker (only in the service position, the maintenance position could operating breaker).
Although below in conjunction with the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
