Problems solved by technology

[0002] After the comprehensive automation transformation of the substation, the operator controls the KK control switch more frequently, and the appearance of the KK control switch is all the same, which makes it very easy for the operator to misoperate the KK control switch, resulting in mis-distribution or mis-closure. and construction bring great potential safety hazards, and cannot fully guarantee the transmission safety of power lines

Embodiment Construction

[0007] The embodiment will be described in detail with reference to the drawings. A control switch includes a switch body 2 and a keyhole member 3. A protrusion 1 is provided on the switch body, and a hole 4 matching the protrusion is provided on the keyhole member. When the present invention is used, the position of the bumps on the switch body of different lines is different. For example, according to the design of the clock, bumps are provided in the 12 o'clock direction, 1 o'clock direction, or 2 o'clock direction. The opening position of the keyhole piece corresponding to the line switch body is also the position corresponding to the bump, so when the small KK control switch is operated, the small KK control switch corresponding to each line is different, even if the operator takes the wrong small KK control switch. The KK control switch can not be inserted into the key hole, and the line cannot be operated, which can effectively avoid the misconnection or misdivision of th...

Abstract

The invention discloses a control switch and aims to design a control switch which difficultly causes error operation. The technical solution is that: the control switch comprises a switch body and a key hole part; the switch body is provided wit a bump; and the key hole part is provided with a hole matched with the bump. The control switch has simple structure, and can effectively prevent incorrect closing or incorrect opening of electric power circuit, so as to ensure safety operation of the electric power circuit.

Description

Technical field: [0001] The invention relates to a control switch of a substation, in particular to a control switch. Background technique: [0002] After the comprehensive automation transformation of the substation, the operator controls the KK control switch more frequently, and the appearance of the KK control switch is all the same, which makes it very easy for the operator to misoperate the KK control switch, causing misdivision or misconnection, and power supply And construction brings great safety hazards, and the transmission safety of power lines cannot be fully guaranteed. Summary of the invention: [0003] The purpose of the present invention is to design a control switch that is not prone to misoperation. [0004] The technical solution of the present invention is a control switch, which includes a switch body and a keyhole member, and is characterized in that a convex block is provided on the switch body, and a hole matching the convex block is provided on the key...
