Summary of the invention
The invention will solve existing switch casing and not include current transformer in casing, user uses interval and power supply management interval mixing, easily cause the problem of managerial confusion, a kind of outdoor temporary electricity utilization metering management switch case is provided, this device can include current transformer in casing, extend the serviceable life of current transformer, various type mutual inductor can be changed flexibly, eliminate stealing risk.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: outdoor temporary electricity utilization metering management switch case, comprise switch casing and be positioned at the fixed cross beam of described switch casing, current transformer, electricity charge acoustic-optic alarm, electricity consumption master switch, electric energy meter and U-shaped busbar, described fixed cross beam is positioned in the middle part of described switch casing, described switch casing is divided into inlet wire cable interval and outlet cable interval by described fixed cross beam, described U-shaped busbar is positioned at above described fixed cross beam
It is interval that described electric energy meter and described electricity consumption master switch are positioned at described outlet cable, the described switch casing at the interval place of described outlet cable is also provided with outlet cable retaining, the leading-out terminal of described electricity consumption master switch connects one end of outlet cable, the other end of described outlet cable draws described switch casing by described outlet cable retaining
It is interval that described current transformer and described electricity charge acoustic-optic alarm are positioned at described inlet wire cable, and described current transformer is connected with described fixed cross beam, the described switch casing at the interval place of described inlet wire cable is also provided with inlet wire cable protection port, and the coil passing described current transformer from the inlet wire cable of described inlet wire cable protection port introducing is connected with described U-shaped busbar.
Further, described U-shaped busbar is orthogonal with described fixed cross beam, and the side of described U-shaped busbar is connected with the end of incoming cables of described electricity consumption master switch, and the opposite side of described U-shaped busbar is connected with described inlet wire cable.
The advantage that the invention has and good effect are: outdoor temporary electricity utilization metering management switch case, by changing switch casing internal space design and structure, effective differentiation inlet wire, go out space of lines, make between directorial area distinct, indirectly reduce the situation of the damage of electric power meter, precision reduction, improve plant running degree of stability, reduce maintenance probability, and give electricity consumption enterprise and comparatively simply use interface clearly.The invention in actual use, because switch casing and each component structure are arranged between two spaces, avoid and form the situation generations such as error connection management space is chaotic, reduce stealing risk, avoid the aging of the outdoor operation of current transformer and damage hidden danger, effectively reduce stealing risk.
