Abstract
The utility model relates to a grounding interlocking mechanism of an electrical cabinet, and the grounding interlocking mechanism comprises a cabinet body and grounding switches which are arranged inside the cabinet body. The cabinet is provided with a separating-reclosing operating rod, an operating panel and a rear door panel interlocking mechanism; the operating panel is in shaft connection with the cabinet, and the separating-reclosing operating rod is connected with the operating panel; the rear door panel interlocking mechanism is movably connected with a shaft sleeve connecting lever on the grounding switch; and the operating panel is connected with a connecting rod which is arranged between the grounding switches and can push the grounding switches to close or open when the operating panel is rotated. Before the repairing work, the separating-reclosing operating rod is pulled by the working personnel after the cabinet is powered off, the separating-reclosing operating rod drives the operating panel to rotate, and the connecting rod drives the rear door panel interlocking mechanism and the grounding switch when the operating panel rotates. The grounding interlocking mechanism has advantages of simpleness in structure, low cost, strong reliability, capability of effectively avoiding the electric-shock accident caused by the misoperation in repairing, and the like.
Description
Technical field
The utility model relates to the chain rack of ground connection of a kind of interlocking gear of electric equipment, particularly a kind of electric cabinet.
Background technology
Electric cabinet is to be widely used in high pressure, the low-voltage power supply system, is used to settle different electric equipments such as circuit breaker.When maintenance repair and maintenance of equipment, the maintenance personal need carry out ground connection with electric cabinet, and existing design is equipped with earthed switch, but does not form interlocking with Rear Door.Just utilized procedure lock guarantee equipment power failure, send electric operating sequence.
On existing design; Though be provided with earthed switch, normally interruption maintenance, safeguard discharge operation safety, when in a single day the staff misoperation occurs; Earthed switch does not also have combined floodgate that the surplus electric weight of equipment is discharged with leading; Carry out inspection operation with regard to directly opening the back door, be easy to like this caused electric shock accidents by surplus electric the arriving on the equipment.Even used procedure lock on the equipment, but the equipment that can only guarantee does not discharge less than earthed switch under forcing at power down mode with leading.
In sum, need a kind ofly can after the maintenance personal opens electric cabinet, can guarantee the interlocking device of rack reliable ground at present, and can be installed in the electric cabinet narrow space.
The utility model content
The utility model technical problem to be solved is shortcomings such as present employed electric cabinet fail safe is low, earthing mechanism complex operation, easy error, designs a kind of chain rack of ground connection of electric cabinet again.
The utility model is realized above-mentioned purpose through following technical scheme:
To the technical disadvantages that the earthing mechanism that has electric cabinet now exists, design a kind of chain rack of ground connection of electric cabinet again, comprise cabinet and the earthed switch that is arranged in the rack.Be provided with a deciliter circle action bars, operation board and Rear Door interlocking gear with rack; Described operation board and rack are coupling, and a deciliter circle action bars is connected with operation board; Axle sleeve connecting lever on described Rear Door interlocking gear and the earthed switch flexibly connects; Be connected through promoting the connecting rod that earthed switch leaves or close when the rotary manipulation dish between operation board and the earthed switch.Before carrying out maintenance work, the staff spurs deciliter circle action bars after cutting off the rack power supply, and deciliter circle action bars drives an operation board and rotates, and operation board passes through connecting rod drive Rear Door interlocking gear and earthed switch when rotating.
Described earthed switch is made up of support, earthed switch fixed contact, earthed switch moving contact, axle sleeve connecting lever and spring positioning device; Described earthed switch fixed contact is fixedly connected with support, and earthed switch moving contact and axle sleeve connecting lever are coupling through earthed switch main shaft and support activity; The two ends of described spring positioning device are coupling with support and earthed switch moving contact respectively.When opening the cabinet operation, the earthed switch fixed contact of earthed switch and earthed switch moving contact are closed, carry out ground connection and discharge dump energy in the rack.Also be the release of Rear Door interlocking gear simultaneously, let the Rear Door of rack open.
Described axle sleeve connecting lever is made up of rotating disk connecting lever and chain connecting lever, and an end of rotating disk connecting lever and connecting rod is coupling, and an end of the chain arm of chain connecting lever and Rear Door interlocking gear is coupling.Rotating disk connecting lever and chain connecting lever through the axle sleeve connecting lever are realized the operation that rack ground connection and Rear Door release are carried out synchronously.
The utlity model has simple in structure, lower, the good reliability of cost, the advantages of having brought in the time of can effectively avoiding the misoperation maintenance such as electric shock accidents.
