Open circuit prevention electrical connector

Abstract

The invention discloses an open circuit prevention electrical connector. A bridging block assembly is arranged between each single end bridging sheet of the electrical connector and the extending partof an adjacent three-end bridging sheet; a bridging block is used for connecting and conducting a pair of adjacent single end bridging sheets and the extending part of the three-end bridging sheet under the effect of bridging springs, so that a pair of adjacent transition inserting hole conductors are mutually conducted. When a CT secondary side conducting wire is connected with the pair of transition inserting hole conductors, two ends of a CT certain phase winding are bridged; the certain phase winding of the CT secondary side end form a closed loop; meanwhile, the transition inserting holeconductors on the three extending parts of the three-end bridging sheet are connected with grounding inserting hole conductors in grounding through holes. Therefore when the grounding inserting holeconductors are grounded, and the CT secondary side conducting wire and the pair of adjacent transition inserting hole conductors are connected, the CT certain phase winding forms the closed loop and is bridged with the ground; the CT secondary side open circuit can be prevented; the CT secondary side is grounded in one point in a concentrated way.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to an anti-open circuit electrical connector. Background technique [0002] During the construction of power system substations, the electrical connections between various equipment and control devices are usually connected by terminal blocks at the substation site. Due to the harsh environmental conditions of the substation project construction site, affected by adverse factors such as high temperature, severe cold, rain, snow, and sandstorms, the workload of on-site electrical wiring is huge, the wiring time is very long, the error rate of on-site wiring is high, and repairs are frequent, which seriously restricts the substation construction period. The progress of joint commissioning and testing between equipment and the quality of the entire substation project. For this reason, the "plug and play" technology for electrical connection of smart substations is proposed. The sig...

In view of the fact that the open circuit of the secondary circuit of the current transformer will endanger the safety of people and equipment, the prefabricated cable connectors widely used at present, whether they are circular or rectangular, adopt the straight-through voltage plug-in connection method, which cannot meet the protection requirements of the CT current circuit. Open circuit and bridging of adjacent current loops with only one point of centralized grounding required
