Abstract

The invention provides a busway connector with high protection level, which is provided with a positioning boss to ensure reliable and fast installation of the connector and stable dimensions; a waterproof sealing ring and a waterproof sealing strip are provided, which can play a better waterproof effect. , to ensure that the connector is in a dry state, avoid short circuit between lines, and the protection level can reach IP65; the maximum torque of the torque bolt is 70Nm, the torque value is high, and the performance is stable; the four-corner nut is located at the opening of the limit slot. This structure can ensure that the nut will not rotate with the bolt during the process of screwing the torque bolt, so that the tightening operation is more convenient; the torque bolt is provided with an inner head, an outer head, and a gasket. , the outer head will be disconnected, so the installation is convenient without torque wrench inspection. The setting of the gasket can prevent the staff from carelessly clamping and screwing the outer head and inner head of the torque bolt with a wrench at the same time, resulting in the occurrence of the outer head Unbreakable condition.

Description

technical field [0001] The invention relates to power transmission equipment, in particular to a bus duct connector with high protection level. Background technique [0002] In the existing power transmission bus system, the structure of the bus duct connector is usually composed of two upper and lower side plates, two bowl pads, square nuts and high-strength constant torque bolts and other materials. Although the side plates are processed by aluminum plates, the side plates There are no waterproof grooves on both sides of the board. This structure makes the connection part easy to seep into water during use, which affects the safe operation of the equipment. Therefore, it is usually necessary to apply sealant at the connection between the connecting plate and the busbar after the busbar is connected, which further increases the installation workload, and During the operation of the equipment, the sealant is also easy to age and fall off, so the waterproof effect cannot be ...
