Transformer substation knife switch stabilizing assembly based on isoelastic principle

Abstract

The invention relates to the technical field of substation knife switches, and discloses a substation knife switch stabilizing assembly based on an isoelastic principle, which comprises a support frame, wherein a support rod is fixedly connected to the bottom of the support frame, a static knife switch is fixedly connected to the bottom end of the support rod, and an upper arm frame is fixedly connected to the inner side wall of the support frame. One end of the upper arm frame is movably connected with an upper fixing base, and the interior of the upper arm frame is fixedly connected with a telescopic spring. According to the isoelastic principle, when a vibration source vibrates, the resonance frequency of the vibration filtering system is similar by adjusting the resonance frequency of the vibration filtering system, so that vibration is filtered and the pressure at the upper arm frame and supporting force at the lower arm frame are filtered through deformation of the upper arm frame and the lower arm frame; therefore, stress of the supporting frame is kept balanced. The invention further solves the problem that after the support frame and the static knife switch are opened and closed for a long time, the joint is easy to loosen, and the service life of the knife switch is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of substation knife switches, in particular to a substation knife switch stabilizing component based on the principle of equal elasticity. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation, whose function is to boost the electric energy generated by the generator and feed it to the high-voltage power grid. At present, in the substation system, the connection of the circuit involves the switch, so the stability of the switch , determines the service life of the circuit. [0003] In the prior art, in order to keep the knife switch elastic, the knife switch is generally fixed directly to the support component by a spring. When opening and closing the knife switch, the force generated by the knife switch is directly transmitted to the supp...

Problems solved by technology

[0005]Aiming at the deficiencies of the prior art, the present invention provides a stabilizing component for the switch of a substation based on the principle of equal elasticity, which can open and close the switch by using the principle of equal elasticity The generated vibration is filtered so that the force generated on the static knife gate will not be transmitted to the supporting component, so that the connection is not easy to loosen and the service life of the knife gate is improved. Utilizing the principle of injection and suction, the advantage of automatic spraying of chemicals solves the problem that when the knife switch is opened and closed, the force generated by the knife switch is directly transmitted to the support component by the spring, which leads to the long-term contact between the support frame and the static knife switch. After opening and closing, the connection is easy to loosen. At the same time, when opening and closing, the lubricant cannot be sprayed automatically, and manual spraying is required, which is time-consuming and labor-intensive.
