Abstract
The utility model discloses a novel fail-safe prevention interlocking mechanism for a high-voltage switch cabinet, comprising an interlocking installation rack, an interlocking bent board and a micro switch, wherein the micro switch is locked on a switch baffle by screws. The novel fail-safe prevention interlocking mechanism for the high-voltage switch cabinet is characterized by also comprising a stop pin, an interlocking rod and a resetting spring, wherein the resetting spring is sheathed outside the interlocking rod, the interlocking bent board is articulated with an interlocking support which is fixed on the switch baffle by screws, and the stop pin is connected with the interlocking board through the interlocking rod. The utility model solves the problems of unnecessary power failure caused by passively interlocking and breaking a circuit breaker in mistake, invalid interlocking caused by insufficiently avoiding the rigidity of the interlocking structure of the rigid connection and the like, and effectively stops incidents caused by misoperations and unnecessary power failure caused by breaking the circuit breaker in mistake. The interlocking scheme of the utility model can obviously enhance the power supply quality.
Description
Technical field
The utility model relates to a kind of interlock, particularly relates to a kind of novel high-pressure switch cubicle that can significantly improve power supply quality and prevents interlocking devices with five.
Background technology
At present along with the user to the improving constantly of electricity consumption quality requirement, existing passive chain scheme exists mistake to divide the hidden danger of circuit breaker in high-tension switch cabinet, though mistake divides circuit breaker can not cause the accident, unnecessary power failure has reduced power supply quality significantly; While more has the chain scheme of rigidity deficiency to cause chain inefficacy and causes the accident.Be badly in need of a kind of simple in structurely, convenient make and install, can effectively stop the novel chain scheme that accident that misoperation causes and mistake are divided the unnecessary power failure that circuit breaker causes, the novel high-pressure switch cubicle that power supply quality can be significantly improved is prevented interlocking devices with five.
Summary of the invention
At the problems referred to above, main purpose of the present utility model is to provide a kind of novel high-pressure switch cubicle that can significantly improve power supply quality to prevent interlocking devices with five, the utility model solves above-mentioned technical problem by following technical proposals: a kind of novel high-pressure switch cubicle is prevented interlocking devices with five, it comprises chain installing rack, chain bent plate, sensitive switch, described sensitive switch is locked on the switch dividing plate by screw, it is characterized in that: described interlock also comprises backing pin, latch lever, back-moving spring, described back-moving spring is enclosed within the latch lever outside, described junction panel links to each other by described backing pin with described latch lever, described chain bent plate is hinged on the chain installing rack, and chain installing rack adopts screw to be connected on the switch dividing plate.
Wherein, described screw is a hexagon socket cap head screw.
Wherein, described chain installing rack is the flap that mechanical latching prevents the mistake closing by hand.
Operating principle of the present utility model is as follows: when circuit breaker is in gate-dividing state, mechanical latching can be got to the disjunction locked position of coupler, latch lever moves upward, the drive junction panel moves upward, and chain bent plate rotates up the spring pivot that tangles on the combined floodgate bent plate, switches the locked position of coupler sensitive switch simultaneously, machinery, electric blocking closing circuit, circuit breaker can not close a floodgate, and this moment can disconnecting switch operation, prevents the on-load disconnecting switch operation.When mechanical latching is got to the service position, under action of reset spring, junction panel, latch lever move downward, and it is downward to drive chain bent plate, switch sensitive switch, and the closing circuit conducting can electric, machinery combined floodgate.
When circuit breaker was in closing position, the connecting lever pin that is connected on the switch macro-axis blocked backing pin, and latch lever can't move upward, i.e. mechanical latching forced blocking can't be got to disjunction locked position of coupler operation isolation knife, satisfies the locking requirement.
Positive progressive effect of the present utility model is: the utility model has solved the unnecessary power cut problem that passive interlocking mistake divides circuit breaker to cause, rigidity be connected the problems such as chain inefficacy that structure avoids linkage structure rigidity deficiency to cause, effectively stop misoperation accident that causes and the unnecessary power failure that by mistake divides circuit breaker to cause, this novel chain scheme can significantly improve power supply quality.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.Fig. 1 is a structural representation of the present utility model, Fig. 2 is a local enlarged diagram of the present utility model, the utility model comprises chain installing rack 2, sensitive switch 1, this sensitive switch 1 is locked on the switch dividing plate by the hexagon socket cap head screw of M4*30, this interlock also comprises backing pin 4, latch lever 5, back-moving spring 6, this back-moving spring 6 is enclosed within latch lever 5 outsides, this junction panel 3 links to each other by backing pin 4 with latch lever 5, and this chain installing rack 2 prevents the flap of mistake closing by hand for mechanical latching in practice.
Operating principle of the present utility model: when circuit breaker is in gate-dividing state, mechanical latching can be got to the disjunction locked position of coupler, latch lever 5 moves upward, drive junction panel 3 and move upward, chain bent plate 8 rotates up the spring pivot 7 that tangles on the combined floodgate bent plate, switches locked position of coupler sensitive switch 1 simultaneously, machinery, electric blocking closing circuit, circuit breaker can not close a floodgate, and this moment can disconnecting switch operation, prevents the on-load disconnecting switch operation.When mechanical latching is got to the service position, under the effect of back-moving spring 6, junction panel 3, latch lever 5 move downward, and it is downward to drive chain bent plate 8, switch sensitive switch 1, and the closing circuit conducting can be electric, machinery closes a floodgate.
When circuit breaker was in closing position, the connecting lever pin 9 that is connected on the switch macro-axis blocked backing pin 4, and latch lever 5 can't move upward, i.e. mechanical latching forced blocking can't be got to disjunction locked position of coupler operation isolation knife, satisfies the locking requirement.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
