Abstract
The utility model aims to overcome defects, existing in a grounding system in a box body of an existing high-voltage metering box, that assembling efficiency is affected because installation and fastening steps of a grounding wire need to be added to assembling working procedures of the box body and a combined-transformer installation bottom plate, that an overlong grounding wire makes cost be increased, that insulating strength and voltage-resistant strength are also influenced because the grounding wire is bent in the box body, and that a too short grounding wire causes increased assembling difficulty, waste of assembling time and the like. The utility model provides a grounding device in a box body of a high-voltage metering box. The device comprises a combined-transformer installation bottom plate equipped with bolts and installed in the box body. The housing of a voltage and current transformer in the high-voltage metering box and a secondary grounding terminal of the transformer are connected to the bolts on the combined-transformer installation bottom plate through cooper wires. The grounding device is characterized in that upper plug copper bars are fixed to the combined-transformer installation bottom plate, and lower plug cooper bars used with the upper plug copper bars are fixed in the box body. The grounding device in the high-voltage metering box is fixed into the high-voltage metering box, time is saved when assembly is performed, assembling efficiency is improved, and product quality of the high-voltage metering box can be improved.
Description
Technical field
The utility model relates to a kind of improved earthing device, is with to be fixed on earthing device in high pressure measurement box body relevant concretely.
Background technology
In high pressure measurement box body, be fixed with earthed system in casing, when High-voltage measuring box is installed in operational network, the earthed system in high pressure measurement box body is connected with external ground system, to guarantee the safe operation of High-voltage measuring box.Earthed system in known high pressure measurement box body comprises and being arranged in casing, with the combination transformer mounting base of bolt, is fixed on the voltage in high pressure measurement casing, shell and the mutual inductor secondary ground terminal of current transformer is connected to by copper cash on the bolt of combination transformer mounting base; Casing inner face at High-voltage measuring box is provided with coupling bolt, and ground wire is connected between combination transformer mounting base and casing.Earthed system in this existing high pressure measurement box body has following defect in practical operation: the one, and the installation that need to increase ground wire in the operation of assembling casing and combination transformer mounting base is fastening, affects efficiency of assembling; The 2nd, be connected in the long cost that not only increased of ground wire between combination transformer mounting base and casing, also can, because of bending in casing, affect dielectric voltage withstand intensity; Ground wire is too short can increase assembly difficulty, waste installation time.
Summary of the invention
The installation that need to increase ground wire in the operation of assembling casing and combination transformer mounting base existing for the earthed system in existing high pressure measurement box body is fastening, affects efficiency of assembling; The long cost that not only increases of ground wire, also can, because of ground wire bending in casing, affect dielectric voltage withstand intensity; The too short assembly difficulty that can increase again of ground wire, the defects such as waste installation time, the utility model provides the earthing device in a kind of High-voltage measuring box, earthing device in this High-voltage measuring box is fixed in High-voltage measuring box, when assembling, save time, improve efficiency of assembling, and can improve the product quality of High-voltage measuring box.
For realizing the purpose of this utility model, taked following technical scheme:
Earthing device in a kind of high pressure measurement box body, this device comprise be arranged in casing, with the combination transformer mounting base of bolt, voltage in High-voltage measuring box, the shell of current transformer and mutual inductor secondary ground terminal are connected to by copper cash on the bolt of combination transformer mounting base, it is characterized in that on combination transformer mounting base, being fixed with the copper bar of pegging graft, in casing, be fixed with on the matching used lower grafting copper bar of copper bar of pegging graft.
Feature of the present utility model is simple in structure, easily realization, and cost is low, is easy to promote; Its remarkable advantage is at assembled, to save time, improve efficiency of assembling, and can improve the product quality of High-voltage measuring box.
