Agricultural outdoor protective type junction box

Abstract

The invention provides an agricultural outdoor protective type junction box. The agricultural outdoor protective type junction box comprises an inner junction box and an outer protective box, wherein the inner junction box is arranged in the outer protective box which is fixed on a galvanized flat iron fixed cross arm; an insulation installation plate is fixed in the inner junction box via a fixing screw; a residual-current circuit breaker is installed above the insulation installation plate; four wiring columns are installed below the residual-current circuit breaker; copper core leads are installed between the lower port of the residual-current circuit breaker and the upper ports of the four wiring columns; the bottom of the inner junction box is provided with an inner wire inlet and four inner wire outlets. According to the invention, the wiring problem for temporary electricity utilization of rural irrigation and drainage and harvesting and degranulation is solved; the agricultural outdoor protective type junction box is installed on a farmland electric pole, so that the electricity using accidents are reduced; the agricultural outdoor protective type junction box is simple and easy to install, is convenient in wiring, and is safe and reliable; the outer protective box reliably prevents the inner junction box form being affected and damaged by external force or severe weather.

Description

technical field [0001] The invention relates to the technical field of agricultural electricity use, and more specifically, relates to an agricultural outdoor protective junction box. Background technique [0002] After two reforms of the country's rural power grids, rural low-voltage power grids have been installed in the fields. During the busy season of farming, the random connection of small motors for irrigation, harvesting, and threshing is serious. Some people tie the bakelite knife switch to the pole for wiring for convenience, and some people simply bend the wire into a hook. It is used on the rural low-voltage power grid. Since the rural low-voltage power grid uses three-phase four-wire bare aluminum conductors, which are only 3 meters above the ground, if you are not careful when wiring, it is extremely easy to cause short circuit and equipment damage. , What is more serious is to cause personal electric shock accidents. [0003] The outdoor environment is harsh...

Problems solved by technology

During the busy season of farming, the random connection of small motors for irrigation, harvesting, and threshing is serious. Some people tie the bakelite knife switch to the pole for wiring for convenience, and some people simply bend the wire into a hook. It is used on the rural low-voltage power grid. Since the rural low-voltage power grid uses three-phase four-wire bare aluminum conductors, which are only 3 meters above the ground, if you are not careful when wiring, it is extremely easy to cause short circuit and equipment damage. , more serious is to cause personal electric shock accidents

[0003] The outdoor environment is harsh, and outdoor rural low-voltage electrical equipment is vulnerable to external force or bad weather due to weather or human factors.
