Electrical power high-low voltage complete equipment of prefabricated substation

Abstract

The invention provides electrical power high-low voltage complete equipment of a prefabricated substation. The electrical power high-low voltage complete equipment comprises a distribution box, a high-low voltage control box, a protection box and a placement groove, wherein the bottom part of the distribution box and the bottom part of the high-low voltage control box extend into the placement groove, the bottom part of the distribution box and the bottom part of the high-low voltage control box are respectively provided with a fifth return spring and a sixth return spring, an insertion hole is formed in the left side face of the distribution box, a first rotating half shaft is arranged on the left side face in the distribution box, the right portion of the first rotating half shaft is connected with the left end of a rotating shielding plate, a side transverse plate is fixed to the right end of the rotating shielding plate, a second rotating half shaft is arranged on the upper side face of the side transverse plate, the top part of the second rotating half shaft is connected with the bottom end of a middle rod, and the top end of the middle rod is fixedly connected with the bottom end of a first return spring. According to the electrical power high-low voltage complete equipment, the technical problems that in the prior art, the mechanical energy voltage supplementing capacity is not achieved, high and low voltage flexible adjustment cannot be achieved, and automatic power off in a fire disaster cannot be achieved are effectively solved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a complete set of high and low voltage electric power equipment of a prefabricated substation. Background technique [0002] High-voltage complete equipment refers to indoor and outdoor AC switchgear operating in a power system with a voltage of 3kV and above and a frequency of 50Hz and below. It is mainly used for the control and protection of power systems (including power plants, substations, power transmission and distribution lines, and industrial and mining enterprises). When the line fails, the faulty part is quickly removed from the grid, so as to ensure the normal operation of the fault-free part of the grid and the safety of equipment and operation and maintenance personnel. Low-voltage complete sets of equipment are widely used in power distribution, electric transmission and automatic control equipment of low-voltage systems in power plants. In rece...
