Problems solved by technology
The existing self-injection equipment box is a unified box body. The power line and the backup line are arranged in the same box body, and the inlet and outlet holes are the same line hole, which will cause the insulation layer to age due to heat between multiple wires. Or only one person can operate during maintenance, which reduces work efficiency

The invention discloses a safe automatic switching equipment box, and relates to the field of distribution network equipment. The safe automatic switching equipment box is characterized in that a mainincoming cable box is arranged at one end of a standby automatic switching equipment box and a standby power supply cable box is arranged at the other end of the standby automatic switching equipmentbox; a main power supply incoming cable enters into the main incoming cable box through a through hole A in the bottom of the main incoming cable box to be connected with a main incoming switch lowerpile; a through hole B between the main incoming cable box and the standby automatic switching equipment box is provided with a through-wall knob insulator; a main incoming switch upper pile is connected with one end of standby automatic switching equipment through a busbar A; the standby power supply incoming cable enters into the standby power supply cable box through a through hole D in the bottom of the standby power supply cable box to be connected with a standby power supply switch lower pile; a through hole C between the standby power supply cable box and the standby automatic switching equipment box is provided with a through-wall knob insulator B; a standby power supply switch upper pile is connected with the other end of the standby automatic switching equipment through a busbarB; the standby automatic switching equipment is connected with an outgoing cable; and the outgoing cable passes through a through hole formed in the bottom of the standby automatic switching equipment box.
Description
technical field [0001] The invention relates to the field of distribution network equipment, in particular to a safe self-switching equipment box. Background technique [0002] In the power industry, with the further improvement of the distribution network system, there are more and more power distribution equipment. In order to ensure the reliability of power supply and minimize the loss caused by power failure, the backup power automatic input device is used in many places, such as Factories, schools, large-scale event venues, office spaces, important users, various power protection sites, etc. The existing self-injection equipment box is a unified box body. The power line and the backup line are arranged in the same box body, and the inlet and outlet holes are the same line hole, which will cause the insulation layer to age due to heat between multiple wires. Or only one person can operate during maintenance, which reduces work efficiency. Contents of the invention ...
