Abstract

The invention discloses a drawer-type intelligent comprehensive low-voltage distribution JP cabinet. A three-phase air switch is arranged inside a main inlet wire unit cell, and is connected with a inlet wire copper row terminal of a drawer unit cell through a copper row of an insulation cell; a lightning protection control unit cell is provided with an emergency lighting control switch, an emergency lighting control breaker, a surge control breaker, a surge protector, and a temperature controller which are arranged on an insulating spacer; the drawer unit cell comprises four drawer units, wherein a drawer operation panel, a remote leakage protection switch and an outlet wire panel are respectively arranged in the three upper drawer units and the lowest drawer is a reactive compensation drawer unit; and a measurement unit cell is equipped with a metering device and a remote terminal control system, and the measuring result can be transmitted to a computer terminal through a GPRS. The drawer-type intelligent comprehensive low-voltage distribution JP cabinet can greatly save space, improve the overhaul interchangeability of the distribution cabinet, improve the protection of the personnel and the security of the equipment on the one hand, and on the other hand enable the on-site operation to be simple, fast, and reliable.

Description

technical field [0001] The invention relates to the technical field of low-voltage power distribution equipment in power systems, in particular to a drawer-type intelligent comprehensive low-voltage power distribution JP cabinet. Background technique [0002] Low-voltage power distribution cabinets go deep into production sites, public places, residential buildings and other places. It can be said that all places where electrical equipment is used must be equipped with this equipment. The development of low-voltage power distribution cabinets is rooted in the material industry, low-voltage electrical, processing technology and equipment. , infrastructure construction and people's living standards, so the level of low-voltage power distribution cabinets reflects a region's economic strength and scientific and technological living standards from one aspect. With the increase of residential electricity load and the continuous improvement of the safe electricity consumption ...
