Buried and opened distribution box and application thereof

Abstract

The invention relates to a buried and opened distribution box and application thereof. A pit box buried underground and provided with an upward opening is included. A junction box is arranged in the pit box. A box cover is articulated with the upward opening of the pit box. A distribution box is arranged at one side of the box cover facing towards the inner cavity of the pit box. A power input terminal and a power output terminal are arranged on the junction box. The power input terminal is connected with an external power supply through a power line. The power output terminal is connected with the distribution box through an adjustable power connection line. The power line passes through a small hole arranged on the other side wall of the pit box and extends in the pit box. The power line and the small hole are arranged in a sealed manner. By utilizing the buried and opened distribution box disclosed by the invention, the power can be used at any time; because no disorder power line exists on the ground, the tripping problem can be avoided; any temporary installation is unnecessary; after the buried and opened distribution box is used, a system is convenient and rapid to turn off; the more reliable safety is provided for operation vehicles, vehicles and pedestrians; and, when being not used, the buried and opened distribution box is nearly hidden completely.

Description

technical field [0001] The invention relates to a distribution box, in particular to a buried and openable distribution box and its application. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions.

AI Technical Summary

Problems solved by technology

[0003] Most of the distribution boxes are installed on the ground, so the power lines will also be exposed on the ground, so that the excessive lines appear messy; and usually most of the occasions where the distribution boxes are used temporarily are densely populated, so the exposed power supply There are potential safety hazards in the line, and problems such as winding or tripping may occur

Furthermore, for the occasions where electricity is temporarily needed, the current distribution box needs to be temporarily installed when it is used, which requires high requirements for those occasions that cannot be temporarily installed.
