Remote control opening and closing device for portable switch cabinet

Abstract

The invention provides a remote control opening and closing device for a portable switch cabinet, and belongs to the field of power. The remote control opening and closing device comprises a supporting base, a power supply assembly and a remote control assembly, wherein a slide rail is formed on the supporting base; an electric push rod assembly sliding along the slide rail is mounted on the sliderail; a worm telescopically moving is arranged in the electric push rod assembly; after the electric push rod assembly is powered on, the worm extends out of the electric push rod assembly to be pressed against an opening and closing button so as to press the opening and closing button to complete an opening and closing operation; the power supply assembly supplies power to the electric push rodassembly; and the remote control assembly controls power-on and power-off of the electric push rod assembly. By using a remote control device for carrying out remote control on the electric push rod assembly, the worm in the electric push rod assembly presses the opening and closing button to complete the opening and closing operation. Relative to the prior art in which the opening and closing operation is completed mutually, by using the remote control opening and closing device provided by the invention, the remote operation can be implemented, and the risk caused by the opening and closingoperation is reduced.

Description

technical field [0001] The invention belongs to the field of electric power, in particular to a remote control opening and closing device for a portable switch cabinet. Background technique [0002] According to past operating experience, there have been many cases of high-voltage short-circuit and discharge phenomena when the switchgear stops power transmission and the circuit breaker opens and closes. With the development of power system automation, the current substation equipment has basically realized remote operation. For the personal safety of the operating personnel, it is required to prohibit the opening and closing operation of the 35 and 10 kV switchgear for on-the-spot shutdown and transmission. The operation can no longer be realized. In this case, it is generally necessary for the operation and maintenance personnel to report to the leader and carry out on-site operation. This method has a high risk factor and is generally not used without emergency, because wh...
