Embodiment approach

[0049] As an implementation, the mobile power supply can be a portable storage battery.

[0050] Further, a corresponding indicator light 13 can also be set on the table of the operation box 10, and signs of "knife switch" and "ground knife" are set beside the indicator light 13 to inform the operator of the current status of the knife switch. For example, when the moving contact 3 is connected to the static contact 4, the indicator light 13 at the "knife switch" is on, indicating that it is currently in the closing state, and when the moving contact 3 is connected to the ground contact 2, the "knife switch" "The indicator light 13 is on, which means that it is in the grounding state at present.

Abstract

The invention relates to the technical field of isolating switches, and discloses a 10kV outdoor electric isolating knife switch. The 10kV outdoor electric isolating knife switch comprises a base, a moving contact, a static contact, a grounding contact and an electric operating mechanism, wherein the electric operating mechanism comprises a motor, a rotating wheel and an insulating connecting rod, the grounding contact, the moving contact and the static contact are sequentially arranged on the base, the moving contact is installed on the base through an insulating supporting piece and connected with the rotating wheel through the motor, the rotating wheel is connected with the insulating connecting rod, the insulating connecting rod is connected with the tail part of the moving contact, and the moving contact is fixed on the top of the insulating supporting piece, so that the moving contact, the insulating connecting rod and the rotating wheel form a lever structure, the lever structure is driven when the motor drives by utilizing a lever principle, and the other end of the moving contact is swung to a switch-on position. The 10kV outdoor electric isolating knife switch is simple in structure, knife switch opening and closing can be achieved, grounding operation can be rapidly achieved when the knife switch is opened, time and labor are saved, and the operation risk of operators is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to a 10kV outdoor electric isolating knife switch. Background technique [0002] In a 10kV distribution network, a 10kV isolation switch is generally installed on the side of the fuse near the line. At the same vertical height, various devices such as isolating switch, fuse, transformer bench (circuit breaker bench) are usually set, and there must be a sufficient safety distance between each other, which leads to the installation of 10kV isolating knife The gate has a higher distance from the ground. [0003] In the traditional technology, the isolation knife switch is manually operated, which is time-consuming and laborious. To solve this problem, the prior art provides a 6-10kV electric isolating switch, and its patent application number is 200910147088.9. The electric isolating switch includes isolating The switch static contact, moving contact, electric operating me...
