Abstract

The utility model discloses an isolation switch, comprising a hollow shaped base, a pillar insulator, a terminal block on the pillar insulator, a conductive arm, and a grounding conductive arm, both ends of the base are respectively fixed the pillar insulator, the terminal seat of one of the pillar insulators is fixed with a support, the support is connected with the conductive arm; the central section of the base is transversely provided with a rotating shaft, the rotating shaft is fixed with a turn arm, the turn arm is connected with the pillar insulator, the upper end of the pillar insulator is connected with the conductive arm; one end of the rotating shaft is connected with the grounding conductive arm. The isolation switch has the advantages of ensuring accurate operation because the pull rod insulator and the shaft of the conductive arm and the rotating axis of the grounding conductive arm are coaxial, avoiding misoperation ensuring good security performance, and avoiding the hidden danger because of the operation mistake of the isolating switch and the grounding switch.

Description

A kind of isolating switch

Technical field

The utility model relates to a kind of isolating switch, particularly a kind of isolating switch that is applicable to isolating switch and earthed switch coenosarc.

Background technology

At present, the isolating switch on the market is a lot, with regard to general isolating switch, because isolating switch and earthed switch can not be coordinated control well, misoperation occurs through regular meeting, and therefore, potential safety hazard is just more outstanding.

Summary of the invention

Of the present utility model provide a kind of simple in structure, can avoid misoperation, isolating switch that security performance is good fully.

In order to solve above technical problem, isolating switch of the present utility model, comprise the pedestal, the post insulator that are hollow form, and junction block, conductive arm and ground connection conductive arm on the post insulator, the two ends of described pedestal are the anchor post insulator respectively, all is connected to junction block on post insulator, and fixed support on the junction block of a post insulator therein, on support, connect conductive arm, and connect the ground connection fixed contact in the outside of support; The horizontal rotating shaft at the middle part of described pedestal, fixing connecting lever in the rotating shaft is connected with post insulator on the connecting lever, and the upper end of described post insulator is connected with conductive arm; End in described rotating shaft is connected with the ground connection conductive arm, and joint is equipped with at two ends.

Described isolator operation axle and earthed switch operating axis are same axle.

The advantage of a kind of isolating switch of above structure is:

1, the connecting lever of cylinder lever connecting rod insulator is coaxial with the ground connection conductive arm, motion by an axle while control pull rod insulator and top conductive arm and ground connection conductive arm, earthed switch closes a floodgate when realizing the isolating switch separating brake, otherwise isolating switch closes a floodgate in the time of the earthed switch separating brake.

2, this isolating switch is because the rotating shaft of the axle of operation link insulator and conductive arm and ground connection conductive arm is coaxial, operates accurately, avoids misoperation, thereby guarantees that security performance is good, stops the hidden danger that is caused by isolating switch and earthed switch operate miss.

3, this isolating switch compact conformation, simple to operation is practical and be suitable for promoting.

4, the shared operating mechanism of isolating switch and earthed switch, this isolating switch cost is low.

Embodiment

As shown in Figure 1, each

anchor post insulator

2,3 all is connected to junction block 4,5 on

post insulator

2,3 at the two ends of pedestal 1, and on the junction block 5 of post insulator 3 fixed support 6, on support 6, connect conductive arm 7, and connect ground connection fixed contact 8 in the outside of junction block 5.

Shown in Fig. 2,3, the horizontal rotating shaft 9 at the middle part of described pedestal 1, fixing connecting lever 10 in the rotating shaft 9, be connected with post insulator 11 on the connecting lever 10, the upper end of this post insulator 11 is connected with conductive arm 7, conductive arm 7 is the grooved conductive arm, and link insulator 11 is on the pivot pin 12 that is connected in the groove when being connected with conductive arm 7.Rotating shaft 9 is connected the rotating shaft 9 of homonymy of ground connection fixed contact 8 with junction block 5 on ground connection conductive arm 13 is housed in addition, joint 14 is equipped with at axle two ends, is used to connect three-pole isolator.

This isolating switch just is fixed on the connecting lever 10 of ground connection conductive arm 13 and drive link insulator 11 conductive arms 7 in the rotating shaft 9 simultaneously like this, when isolating switch in opened condition the time, fingertip on conductive arm 7 and the junction block 4 is separated to safe distance, and ground connection conductive arm 13 just is closure state with ground connection fixed contact 8; When isolating switch was closure state, conductive arm 7 and junction block 4 closures, ground connection conductive arm 13 just were with ground connection fixed contact 8 and are separated to safe distance.This structure because adopt ground connection conductive arm 13 and the connecting lever of operation conductive arm 7 coaxial, therefore can stop the potential safety hazard that causes because of earthed switch and isolator operation error, guarantee the safety and reliability of product.
