Abstract

The utility model provides a mechanical interlocking device of an isolating switch and a ground switch. The mechanical interlocking device consists of a mechanical interlocking component between the isolating switch and the ground switch. Cam disks are respectively fixed at principal rotation axes of the isolating switch and the ground switch, and a return board is connected with the principal rotation axes of the isolating switch and the ground switch above the cam disks. The mechanical interlocking device ensures that the cam disks and the return board move relatively by the movement of a principal axis, so as to realize that triangular slots of the cam disks block a pin at the return board to interlock. The mechanical interlocking device has simple structure and easy operation and interlocks by using the cam disks to block the return board, thereby causing no displacement and avoiding the potential safety hazard caused by interlocking.

Description

The mechanical interlocks of a kind of isolating switch and earthed switch
Technical field
The utility model relates to isolating switch, the earthed switch that a kind of High-Voltage Electrical Appliances are used, the mechanical interlocks of particularly a kind of isolating switch and earthed switch.
Background technology
Isolating switch in the market and the mechanical interlocks between the earthed switch are to adopt on rotation axis with two fanning strips, and the rotation by fanning strip realizes interlocking.Such structure occurs just can making under the situation of misoperation or error in operation fanning strip to skid when rotating the staff, cause out the position, causes security incident; And this switch application is in the high more electric power system of voltage, and the consequence of security incident is serious more.
The utility model content
The utility model provides the mechanical interlocks of a kind of isolating switch and earthed switch, constitute by the cam skateboard construction machine locking part that connects between isolating switch and the earthed switch operating axis, difference stationary cam disk on the main operation axle of described isolating switch and earthed switch, and the operating axis position of isolating switch above cam disk and earthed switch is connected slide plate.
Described cam disk is provided with a triangular groove.
A pin is respectively established at the two ends of described slide plate.
The two ends of described slide plate respectively have an elongated slot.
The advantage of above structure is: this isolating switch and the mechanical interlocks of earthed switch be on main shaft the stationary cam disk be connected mechanical interlock---slide plate, motion by main shaft, make cam disk and slide plate relative motion, the triangular groove of realization cam disk blocks the pin on the slide plate, obtains interlocking.This is simple in structure easy to operate, and blocks slide plate by cam disk and obtain interlocking, can not go out to reveal a phenomenon, has stopped the potential safety hazard that occurs because of interlocking.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation enlarged drawing of the utility model slide plate;
Fig. 3 is the vertical view of slide plate shown in Figure 2;
Fig. 4 is the structural representation enlarged drawing of the utility model cam.
Embodiment
As shown in Figure 1, upper fixed insulator 2 at bearing 1, both sides at bearing 1 connect isolating switch main shaft 5 and earthed switch main shaft 6 by bearing pedestal 3,4 respectively, described isolating switch main shaft 5 and earthed switch main shaft 6 are enclosed within respectively in the action bars 7,8, are with slide plate 13 on isolating switch main shaft 5 and earthed switch main shaft 6; Shown in Fig. 2,3, described slide plate 13 two ends cutting elongated grooves 9,10 also have pin 11,12, and two elongated slots 9,10 of slide plate 13 are enclosed within respectively on the main shaft 5,6, and the diameter of elongated slot can move around on main shaft greater than main shaft.Lower portion difference stationary cam disk 14,15 at isolating switch main shaft 5 and earthed switch main shaft 6 cover slide plates 13; As shown in Figure 4, all have a triangular groove 16 on the described cam disk 14,15, stationary cam disk 14,15 o'clock, the triangular groove 16 of two cam disks is opposing fixing in the time of should remaining on the isolating switch separating brake, like this, guarantee that cam disk 14 blocks pin 11 when running, the triangular groove 16 of cam disk 15 is a released state with pin 12 just.
