Description
Technical Field
The utility model belongs to the technical field of power equipment, a equipotential line device that is used for subway isolator to go up installation is related to.
Background
In summer and autumn, the external environment temperature is high, the line load current is large, the load current borne by the isolating switch is obviously increased at the moment, in addition, the temperature is high, the heat dissipation of the main disconnecting link is difficult, the equipment continuously runs under high load under severe conditions, the temperature of the main disconnecting link of the isolating switch is continuously increased, if the time is due to reasons such as power conservation and the like, the power failure can not be timely maintained, the equipment runs beyond the maintenance period, the ageing of the equipment material and the reduction of the conductive capability are easily caused, the contact of the disconnecting link is overheated, the load is increased due to the change of the running mode of the equipment in a peak period, the continuous temperature of the main disconnecting link is overheated, and even the contact burning loss.
Disclosure of Invention
Aiming at the defects, the utility model aims at providing an equipotential line device with a shunt function for a subway isolating switch when the load is heavy.
In order to achieve the above purpose, the technical scheme of the utility model is that: an equipotential line device of a subway isolating switch comprises 120 soft copper stranded wires, DTM-120 copper terminals, M12X70 bolt assemblies, hexagonal spacing columns, M12X120 bolt assemblies and ties; the two 120 soft copper stranded wires (with the length of 480mm) are connected with one DTM-120 copper terminal at each end to form two copper conducting wires with equal length, one end of each copper conducting wire is fixed on a main disconnecting link of the isolating switch through a hexagonal spacing column and an M12X120 bolt assembly, the other end of each copper conducting wire is fixed on a wire outlet side terminal of the isolating switch through an M12X70 bolt assembly, and then a binding belt is fixed in the middle of the two copper conducting wires to form the equipotential line device of the subway isolating switch. The method is characterized in that: the method comprises the following steps of firstly using two 120 soft copper stranded wires 1 (with the length of 480mm), respectively crimping one DTM-120 copper terminal 2 at each of two ends of each copper wire to form two copper wires with equal length, fixing one end of each copper wire on a main disconnecting link of an isolating switch through a hexagonal spacing column 4 and an M12X120 bolt assembly 5, fixing the other end of each copper wire on a wire outlet side terminal of the isolating switch through an M12X70 bolt assembly 3, and fixing a ribbon 6 at the middle position of the two copper wires to form the equipotential line device of the subway isolating switch.
The technical scheme of the utility model in the length L of 120 soft copper strands put 480 mm.
The utility model discloses the effect is using this subway isolator equipotential line device, the effectual isolator of having solved under the big circumstances of line load heavy current in service, the equipotential line device is installed on the binding post of main switch and play line side, can play the effect of reposition of redundant personnel. A part of current on the main disconnecting link is divided to the wiring terminal on the outgoing line side through the equipotential line, so that the whole conductive capacity of the equipment is enhanced, the load current of the main disconnecting link is effectively reduced, the continuous temperature rise of the main disconnecting link can be effectively relieved, and the safe operation of the equipment is guaranteed.
The utility model has the characteristics of simple structure, convenient to use, connection are reliable.
