Intelligently manufactured capacitor protection device

Abstract

The invention relates to the technical field of capacitor protection devices. The invention further discloses an intelligent manufacturing capacitor protection device. The device comprises a shell, afirst round hole is formed in the left side of the upper end of the shell, a metal wire is movably inserted into the first round hole, a medium is fixedly connected to the upper end of the metal wire,a support is fixedly connected to the middle of the upper end of the shell, a box is fixedly connected to the upper end of the support, a first square hole is formed in the left side of the upper endof the box, and a pipeline is fixedly connected to the right. By pressing the pressing block, the pressing block pushes the wedge block to move downwards; the wedge block drives the connecting rod tomove leftwards along the second square hole, so the second spring is stretched gradually and the intersection part of the first U-type block and the second U-type block is gradually increased; and when the diameter of the intersection is larger than that of the metal wire, the metal wire is inserted from the first circular hole until the lower end of the metal wire is pressed to the first spring,the pressing block is loosened, the connecting rod is pulled back to the initial position by the second spring, and the medium is successfully installed, so that the effect of convenient disassemblyand assembly is achieved.

Description

technical field [0001] The invention relates to the technical field of capacitor protection devices, in particular to an intelligently manufactured capacitor protection device. Background technique [0002] Each capacitor of the existing capacitor bank is equipped with a protection device. As long as the protection and coordination are proper, the faulty capacitor can be quickly cut off to prevent the oil tank of the capacitor from exploding, and the nearby capacitors are protected from damage. The reasons are, one is that the operating voltage is higher than the rated voltage of the capacitor, and the other is the overcurrent caused by harmonics. The capacitor protection device can protect the phase-to-phase short circuit fault on the capacitor lead or trip the emergency switch when the capacitor bank is overloaded. [0003] However, the existing capacitor protection device is not stable enough, and the capacitor voltage protection is not tight enough to ensure the safety o...
