Anti-seismic contact box

Abstract

The invention provides an anti-seismic contact box. The anti-seismic contact box comprises a shell, an anti-seismic plate, a static contact, a moving contact and a bus, wherein the anti-seismic plate comprises a connecting plate, a fixing column, two sliding grooves and a sliding plate, the fixing column is located on one face of the connecting plate, the two sliding grooves are located in the two sides of the other face of the connecting plate respectively, one end of the sliding plate is tightly attached to the connecting plate, and the other end of the sliding plate slides in the sliding grooves. The static contact comprises a grounding binding post, a check ring and a connecting contact. When the contact box is used and vibrates, the sliding plate can slide in the sliding groove, the connecting plate can move relative to the sliding plate, the contact area of the sliding plate and the connecting plate is not changed, and the moving contact is in contact connection with the sliding plate, so that the area change of a current channel between the moving contact and the static contact cannot be caused, and sparks cannot be caused. The problem that when an existing contact box vibrates, a static contact and a moving contact move relative to each other, and consequently the temperature in the contact box rises is solved.

Description

technical field [0001] The application belongs to the field of contact box equipment, and in particular relates to an anti-vibration contact box. Background technique [0002] The high-voltage switchgear is one of the most important parts of the power system. The busbar system installed in the cabinet is connected to the static contact of the circuit breaker device through the contact box. At present, the contact box and the static contact of the existing high-voltage switchgear are both It is in the shape of a sleeve, and the bottom end of the smaller static contact barrel is fixedly installed in the larger contact box. [0003] The existing contact box includes a cylindrical box body, and a female outlet is installed on the upper part of the box body. Its function is to avoid corona discharge and other phenomena caused by the exposed joints and joints of cabinets. However, the existing contact box is basically just a box body, so it is difficult to avoid equipment vibrat...
