Outdoor power switchgear

Abstract

The present invention relates to a novel outdoor power switch. The device comprises a box body, wherein a first insulating post and a second insulating post are separately arranged in the box body; a first wiring holder and a second wiring holder are respectively arranged on the top ends of the first and second insulating posts; an insulating separator is arranged between the first and second wiring holders; a guide rod hole is formed at the center of the insulating separator; the first and second wiring holders are respectively connected with first and second stationary contact pieces; a movable contact piece is arranged below the guide rod hole; a guide rod is arranged at a top end of the movable contact piece; a first spiral spring is connected between the insulating separator and the movable contact piece; a push-pull seat is arranged at a top end of the guide rod; a limit lever is arranged on the insulating separator; the upper part of the left side of the limit lever is connected with a telescopic lever; the left end of the telescopic lever is connected with a limit seat; and a second spiral spring is connected between the limit seat and the limit lever. By adopting the structure above, the novel outdoor power switch apparatus provided by the present invention is capable of effectively ensuring good contact of a switch and greatly guaranteeing safety of operation personnel.

Description

technical field [0001] The invention relates to an outdoor power switch device. Background technique [0002] In the field of electric power, a power switch device is an important on-off control component, which can be used to open a circuit, interrupt a current, or switch a current between different circuits, etc., and thus has been widely used. At present, a large number of power switchgears are used outdoors, and the existing problem is that when the moving contact piece and the static contact piece in the power switchgear are combined to close the switch, they are often partially contacted first (such as point contact or line contact). Contact), and then gradually complete contact, which is not only easy to generate a large spark or arc, but also not conducive to the benign contact between the moving contact and the static contact; at the same time, the moving contact in the existing power switchgear And the static contact pieces are often exposed outside, which can eas...

Problems solved by technology

At present, a large number of power switchgears are used outdoors, and the existing problem is that when the moving contact piece and the static contact piece in the power switchgear are combined to close the switch, they are often partially contacted first (such as point contact or line contact). Contact), and then gradually complete contact, which is not only easy to generate a large spark or arc, but also not conducive to the benign contact between the moving contact and the static contact; at the same time, the moving contact in the existing power switchgear And the static contact pieces are often exposed outside, which may easily cause the operator to accidentally contact when operating the power switch, thus causing serious safety hazards, which greatly affect the performance and safety performance of the power switch device
