In whole high-voltage electric system, measurement problem is a crucial problem, because he is related to power supply administration and the interests by electric unit; And in different systems, the current transformer used and voltage transformer are different, so different metering handcarts need be gone out by the profile arrangement different according to them when designing; The overall dimension of metering switch cabinet also will change according to the difference of metering handcart, brings a lot of inconvenience, also just reduce operating efficiency to design work.
Summary of the invention
Technical problem to be solved by this invention provides a kind of metering handcart for above drawback, and structure is simple, easy to operate, can reach standardisation requirements, add operating efficiency.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of metering handcart, comprise chassis, mounting panel, current transformer, voltage transformer, insulator, connect copper bar, handcart contact arm, fuse and Mume flower contact, described chassis is provided with four rolling, described mounting panel comprises the voltage transformer mounting base be horizontally fixed on chassis and the current transformer mounting panel be vertically fixed on chassis, described voltage transformer mounting base is provided with voltage transformer positioning framework, described voltage transformer is fixed on voltage transformer mounting base by C type strutting piece, be arranged in voltage transformer positioning framework, described current transformer is fixed on current transformer mounting panel by C type strutting piece, stiffener is fixed with between described voltage transformer positioning framework and current transformer mounting panel, described insulator one end is fixed on current transformer, the other end be connected copper bar and be fixedly connected with, described handcart contact arm one end is fixed on and connects on copper bar, the other end is connected with Mume flower contact, described fuse one end is fixed on to connect on copper bar and is connected with current transformer, and the other end contacts with voltage transformer.
Above-mentioned a kind of metering handcart, wherein, the quantity of described handcart contact arm is 2n, and n is positive integer, and handcart contact arm is that being evenly distributed in of 2*n connects on copper bar.
Above-mentioned a kind of metering handcart, wherein, the distance between two handcart contact arms that described longitudinal direction is adjacent is 248mm.
Metering handcart of the present invention can use in different electrical systems, can according to the difference of actual conditions, the current transformer of choice for use different size and voltage transformer, in installation process, voltage transformer mounting base summation current transformer mounting panel can be changed according to different overall dimension, or change the height of C type support, simultaneously, can also according to the handcart contact arm of the different size of the different choice of size of current and Mume flower contact, thus reach standardized requirement, whole device dismounting is simple, easy for installation, the each demand of each occasion can be adapted to, manpower and materials are saved, reduce cost, add operating efficiency.
And if in use damage fuse and Mume flower contact because of current overload, also can change timely fast, maintenance and repair is convenient; Because whole mechanism is mounted on chassis, chassis is also provided with roller, so move very convenient when using, saves human resources.
Be fixed with stiffener between voltage transformer positioning framework and current transformer mounting panel, add mechanical strength of the present invention, install more firm, reliable and stable, improve security performance, ensure that the personal safety of user.
