Title:

POLE TYPE HIGH-VOLTAGE ELECTRICAL APPLIANCE COMBINED SWITCH

Document Type and Number:

WIPO Patent Application WO/2016/065673

Kind Code:

A1

Abstract:

A pole type high-voltage electrical appliance combined switch with a five-prevention interlocking function is designed to solve the technical problem of low degree of integration and modularization in the existing like products. The high-voltage electrical appliance combined switch comprises a pole support (1), embedded poles (2), a spring operated mechanism (3), and an isolated grounding switch operated mechanism (4); the essential parts of the pole type high-voltage electrical appliance combined switch are as follows: every three embedded poles (2) are arranged in a row at the pole support (1); the spring operated mechanism (3) and the isolated grounding switch operated mechanism (4) are integrally connected by a door interlocking element (5) and a mechanism interlocking element (6); the door interlocking element (5), the mechanism interlocking element (6), and a door lock plate (13) are integrally connected, the door lock plate (13) is opposite to an opening half axle pinch plate of the spring operated mechanism (3), and the door lock plate (13) is provided with a door lock pin (14). The door interlocking element (5) moves up and down for respectively opening or closing operating holes of a rocking handle (401) of the isolated grounding switch operated mechanism (4), and a closing operation and a limiting closing operation are performed in corresponding to the closing half-axle pinch plate of the spring operated mechanism (3), and the limiting and opening of the opening half-axle of the spring operated mechanism (3) and a cable chamber door are performed.
