Stating contact box baffle can move up and down along the sliding slot, and contact box baffle lower part is provided with baffle locking jack, described
The lower partition is provided with partition locking jack, is provided with electromagnetic lock below the contact box baffle, the electromagnetic lock includes magnetic
Portion and pin, described magnetic part one end are fixedly connected with the pin, the pin and the baffle locking jack and it is described every
The central axes that plate locks jack are overlapped；
Travel switch on switchgear side wall is set, is provided with moving contact on the travel switch, it is matched with its to connect
Plate is pressed to be set on high-voltage handcart.
Preferably, the travel switch is fixedly installed on the switchgear side wall by mounting plate.
The beneficial effects of the utility model, the utility model are provided with blocking device, and are controlled by travel switch, when maintenance
After high-voltage handcart extraction, travel switch is triggered, baffle forced blocking is locked by pin, can not be opened by external force, high pressure hand
When vehicle promotes, travel switch is triggered, blocking device is opened, and the structure design of the utility model is reasonable, will not expose charging member, is examined
Repair personnel's safe operation, it is entirely avoided the generation of high pressure electric shock accidents.

Specific embodiment
In conjunction with attached drawing, that the utility model is described in further detail is as follows:
Embodiment one
A kind of blocking device of contact box of high-voltage switch cabinet, as shown in Fig. 2, including the contact box gear being arranged on partition 8
Plate 3, two sides are provided with sliding block, and the sliding block is mating is provided with sliding slot, and the contact box baffle 3 can be along the sliding slot
Lower movement.3 lower part of contact box baffle is provided with baffle locking jack 14, and 8 lower part of partition is provided with partition locking and inserts
Hole 13, electromagnetic lock 6 is provided with below the contact box baffle 3, and the electromagnetic lock 6 includes magnetic part and pin 5, the magnetic part
Centre is provided with spring, and described magnetic part one end is fixedly connected with the pin 5.The pin 5 locks jack with the baffle
14 and the partition locking jack 13 central axes be overlapped.
As shown in figure 3, the utility model further includes the travel switch 11 being arranged on switchgear side wall, the travel switch
11 are fixedly installed on the switchgear side wall by mounting plate 12.It is provided with moving contact 10 on the travel switch 11, with it
Matched contact pressing plate 9 is set on high-voltage handcart 7.
The utility model overall schematic is as shown in Figure 1.
When service personnel overhauls, when extracting high-voltage handcart 7 out, main contact 4 is separated with primary band electrical contact 1, exits contact
Box 2, contact box baffle 3 moves down blocks contact box 2 completely.Continue to extract high-voltage handcart 7 out, the contact pressing plate 9 of high-voltage handcart 7 makes
Contact 10 gradually resets, i.e. 11 disconnecting circuit of travel switch.Travel switch 11 disconnects, and the electromagnetic force of electromagnetic lock 6 disappears, pin 5
Insertion baffle locking jack 14 and partition lock jack 13 under spring force, and contact box baffle 3 is locked, to play

Contact 10, closing stroke switch 11, i.e. power on circuitry.Travel switch 11 is closed, and starts electromagnetic lock 6, work of the pin 5 in electromagnetic force
Jack 13 is locked from partition under and baffle locking jack 14 exits, and sliding block moves up, and contact box baffle 3 moves up, high
Pressure handcart 7 normally enters operating position.
The utility model is provided with blocking device, and being capable of forced blocking contact box baffle by travel switch control.Maintenance
When high-voltage handcart extraction after, trigger travel switch, baffle forced blocking locked by pin, can not be opened by external force, high pressure
When handcart promotes, travel switch is triggered, blocking device is opened.The structure design of the utility model is reasonable, low in cost, consolidates peace
Entirely, charging member, service personnel's safe operation will not be exposed, it is entirely avoided the generation of high pressure electric shock accidents.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization.It can be applied to various fields suitable for the present invention completely.For those skilled in the art,
Other modifications may be easily implemented.Therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
