Abstract

The invention discloses a high-current quick-opening body, which is characterized in that the two ends of the insulating sleeve are respectively installed with an end plate of an explosion chamber and an end plate of a storage chamber for connecting to a circuit, and the end plate of the explosion chamber and the end plate of the storage chamber are respectively installed. There is a cylinder in the middle of the end plate, and the front end of the cylinder of the end plate of the blasting chamber is screwed with a plug, and there is a through hole for the lead wire of the explosive in the middle of the plug, and there is a piston bridge between the end plate of the blasting chamber and the cylinder of the end plate of the storage chamber. , the front end of the piston bridge body is connected to the cylinder body of the end plate of the blast chamber, the part between the piston bridge body and the blockage is an explosion chamber filled with explosives, and the rear end of the piston bridge body is inserted into the cylinder body of the end plate of the storage bin, The rear end of the barrel of the storage end plate is a tapered inner hole, which does not allow the piston bridge body to pass through. When the invention is detonated under the action of a control signal, the accuracy rate is high, the amount of explosive is small, and the risk of explosion is small.

Description

technical field [0001] The invention belongs to electric equipment, in particular to a high-current quick-break body in a high-current quick-break device. Background technique [0002] With the continuous growth of the national economy and the increasing prosperity of the market, the demand for energy and power from society and enterprises has risen rapidly. High-power and ultra-high-power electromechanical equipment has become an inevitable choice for the current production industry. The installation of transformers and generators promotes the development of independent power grids. Networking is an effective guarantee for high-power electrical. However, the short-circuit current caused by the super-large load required by high-power electrical appliances increases, exceeding the allowable value of the breaking current equipment, causing motion and thermal damage to some equipment. To solve this problem, many experts and scholars have designed many effective solutions. A c...
