Description
Technical field
The utility model relates to high-voltage intermediate switch cabinet technical field, in particular to a kind of 6kV high-voltage switch cabinet mechanical are anti-
Accidentally locking device.
Background technique
In electric system, after new installation, maintenance, dampness, suspected malfunctions situations such as motor power transmission before, it is necessary to measure winding
Alternate and insulation against ground resistance.Although Insulation test work should be carried out strictly by the requirement of regulation, stringent basis before cabinet door is opened
Compound judgment criterion confirms circuit really in stand-by heat or cold standby state, the openable cabinet door in the errorless rear of circuit dualism number, cabinet
Strict implement electrical verification program after door is opened, but the control of many safety is all by human factor and operation order in whole work process
Process can not prevent security risk completely.And surveying insulated working at present in actual power plant operation is one very cumbersome
And it is easy to appear the work of problem.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technical problem, provide it is a kind of not only safe and reliable but also
Operate the anti-error locking device of 6KV high-voltage switch cabinet mechanical of succinct high-tension motor measurement insulation.
In order to solve the above technical problems, technical solution provided by the utility model is anti-for a kind of 6kV high-voltage switch cabinet mechanical
Accidentally locking device, including cabinet body, the cabinet body front are equipped with switching mechanism, and the cabinet body back side is equipped with cable bin door-plate, special
Sign is: No.1 mechanical lock is installed on the switching mechanism, Insulation test window is installed on the cable bin door-plate, it is described exhausted
Edge testing window side be equipped with No. two mechanical locks, the No.1 mechanical lock and No. two mechanical locks equipped with and only one mechanical lock
Key.
Preferably, the coding of the No.1 mechanical lock and No. two mechanical locks is identical.
The utility model has the advantages that the operating process that can reduce operations staff compared with prior art, simultaneously
Also the accident for reducing operation and service personnel's mistakenly entering charged chamber, improves the security and stability of equipment operation.

It is as shown in the figure: 1, cabinet body, 2, switching mechanism, 3, cable bin door-plate, 4, No.1 mechanical lock, 5, Insulation test window, 6,
No. two mechanical locks, 7, mechanical lock key.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing, a kind of anti-error locking device of 6kV high-voltage switch cabinet mechanical, including cabinet body 1,1 front of cabinet body are set
There is switching mechanism 2,1 back side of cabinet body is equipped with cable bin door-plate 3, it is characterised in that: is equipped with No.1 on the switching mechanism 2
Mechanical lock 4 is equipped with Insulation test window 5 on the cable bin door-plate 3, and 5 side of Insulation test window is equipped with No. two machinery
Lock 6, the No.1 mechanical lock 4 and No. two mechanical locks 6 equipped with and only one mechanical lock key 7.
The No.1 mechanical lock 4 is identical with the coding of No. two mechanical locks 6.
The utility model installs No.1 mechanical lock on general KYN28 high-voltage central-positioned switchgear on switching mechanism,
Insulation test window (such as Fig. 2) is installed additional on the cable bin door-plate of the switchgear back side, and No. two with coding are installed by Insulation test window
Mechanical lock is latched testing window when for operating normally.Two mechanical locks have and only one mechanical lock key.
When switch is at operating position (such as Fig. 1), mechanical lock is latched in operating position, and key can not take out, and avoids charging
Insulation test window is opened, prevents staff into entering into charged intervals.
It is shaken after switching separating brake to testing position (such as Fig. 4), while by circuit breaker lock in testing position, can just pull up No.1
Mechanical lock unlocks No. two mechanical locks with this key, opens Insulation test window, carries out electrical verification and the Insulation test work of motor.
When reverse operating, Insulation test window is closed, key unlock No.1 mechanical lock, cancel switch examination are pulled up in No. two mechanical lock lockings
Position locking is tested, power transmission work is carried out.
Insulation is surveyed without fully opening rear Xiamen, and every suit interlocks and uses different codings, in full factory's system not
It will appear identical coding.Avoid in this way because grounding switch and rear cabinet door locking failure caused by open by mistake rear cabinet door so as to cause
The case where mistakenly entering charged chamber, occurs.
In addition, Insulation test window carries out surveying the precondition of insulated working being that lock for circuit breaker is scheduled on to test after opening
Or inspecting state, then take key to go to open rear window, after rear window is opened, key is not pulled out not come out locking, and has only been overhauled
Key can just be taken out by finishing after locking window unlocks power transmission to breaker to front, so as to avoid there is personnel preceding in back work
Breaker push-in running position is led to the generation of personnel's electric shock accidents by people from side.This time anti-misoperation locking device of installation, can be most
The generation for reducing to limits or preventing maloperation, go to the wrong way phenomena such as interval.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
