[0003] During the use of the existing isolating switch, the two contacts run in contact for a long time, and the surface of the contacts will be covered with oxides due to reasons such as arcing, burning, and oxidation. These oxides will not cover the contacts for a long time. Cleaning will increase the resistance between the two contacts, causing the two contacts to overheat, causing damage to the contacts and reducing the service life of the contacts. Based on this, we propose a disconnector with self-cleaning function

The invention discloses an isolating switch with a self-cleaning function, which comprises a protective box, two transmission rods are symmetrically slidably connected to the side wall of the protective box, and the two transmission rods are set through the side wall of the protective box. The side walls close to each other of the transmission rods are fixedly connected with insulating blocks, the side walls of the insulating blocks are provided with installation grooves, the inner wall of the installation grooves is rotatably connected with a first rod, and the side walls of the first rod are symmetrically fixedly connected to two Two second rods, two contacts are fixedly connected to the side walls of the two second rods, a cleaning mechanism is installed in the installation groove, and the cleaning mechanism includes a chute opened on the inner wall of the installation groove, the chute The inner wall is slidingly connected with multiple cleaning blocks. The cleaning mechanism in the present invention can scrape off the oxides on the surface of the contacts, so as to avoid too much oxides on the contacts, so that the resistance of the contacts is too large during operation, which will cause the contacts to overheat, thereby causing damage to the contacts and reducing the risk of contact. life of the head.
Description
technical field [0001] The invention relates to the technical field of isolating switches, in particular to an isolating switch with a self-cleaning function. Background technique [0002] The isolating switch is the most widely used electrical appliance in high-voltage switchgear. It is used for all levels of voltage, used to change the circuit connection or to isolate the circuit or equipment from the power supply. At present, it is widely used in power plants and substations. [0003] During the use of the existing isolating switch, the two contacts run in contact for a long time, and the surface of the contacts will be covered with oxides due to reasons such as arcing, burning, and oxidation. These oxides will not cover the contacts for a long time. Cleaning will increase the resistance between the two contacts, causing overheating of the two contacts, causing damage to the contacts and reducing the service life of the contacts. Based on this, we propose a disconnector w...
