Abstract
The utility model provides an electronic isolator linkage ground connection insulation against ground device, the one end of the insulating pull rod of this linkage ground connection insulation against ground device is connected with earthing knife -switch, the other end uses bolt and ground connection axle fixed connection, and along with the ground connection rotation of axes, the metal casing that bolt and isolator owner's plug -in strip are passed through to the one end of ground connection insulator is connected fixedly, the other end passes through the bolt and is connected fixedly with ground copper bars, earthing knife -switch passes through insulated wire and ground copper bars bolt fixed connection, form special insulating ground loop, when main plug -in strip closes a floodgate, the earthing knife -switch separating brake, when main plug -in strip separating brake, earthing knife -switch closes a floodgate. The beneficial effects are that this insulator arrangement can provide special ground loop, and the insulation against ground, the withstand voltage 2000KV that is greater than. When earthing device closed a floodgate, the independent ground connection of metal casing can not passed through to the circuit residual voltage to play the function of pressure release, protection. Satisfy the requirement of isolator linkage ground connection on the one hand, can be with circuit survival voltage direct release to the earth.
Description
Technical field
The utility model relates to a kind of electric isolating switch interlock ground connection insulation against ground device.
Background technology
Existing isolating switch linkage grounding device usually and the metal shell shared grounding loop of isolating switch, when earthing device closes a floodgate, in long distance line, residual voltage is released greatly by shared grounding loop, residual voltage pressure release may may be discharged into other equipment with shared grounded circuit on the one hand, causes equipment burnout; There is the potential safety hazard that personnel get an electric shock in grounded circuit simultaneously.
Summary of the invention
For the unsteadiness of performance in prior art, the purpose of this utility model is to provide a kind of electric isolating switch interlock ground connection insulation against ground device, and isolating switch grounding switch is arranged special grounded circuit and insulation against ground.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of electric isolating switch interlock ground connection insulation against ground device, this interlock ground connection insulation against ground device and isolated switch main plug-in strip mechanical chain, wherein: described interlock ground connection insulation against ground device comprises ground insulation, insulated tension pole, grounding switch, grounding copper bar, one end of insulated tension pole is connected with grounding switch, the other end uses bolt to be fixedly connected with grounding shaft, and rotate with grounding shaft, one end of ground insulation is connected and fixed by the metal shell of bolt and isolated switch main plug-in strip, the other end is connected and fixed by bolt and grounding copper bar, grounding switch is fixedly connected with grounding copper bar bolt by insulated conductor, form special insulating ground loop, when main switch cutter closes a floodgate, grounding switch separating brake, when main switch cutter separating brake, grounding switch closes a floodgate.
Described insulated tension pole adopts epoxide resin material to make.
Effect of the present utility model is that this isolating switch interlock ground connection insulation against ground device can provide a Special grounding loop, road; and loop insulation against ground; withstand voltagely be greater than 2000KV; this device and isolated switch main plug-in strip mechanical chain; actuating length is 90 °, adopts insulation parts isolating switch earthing switch blade and isolating switch casing insulation to be isolated, when earthing device closes a floodgate; circuit residual voltage without metal shell independent grounding, thus can play the function of pressure release, protection.Meet the requirement of isolating switch interlock ground connection on the one hand, line residual voltage can be directly released into the earth by earthing device simultaneously.
