Problems solved by technology

However, because there are many wires in the distribution box, once the wires catch fire, they burn very quickly and spread with the wires easily. The above-mentioned patent only uses fire extinguishing sand to extinguish the fire after the open flame burns the pull rope, which has hysteresis and it is too late to extinguish the fire. The wires are easy to cause large economic losses

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Such as Figure 1 to Figure 3 As shown, a distribution box includes a box body 1, a box door 2, and an electrical appliance fixing plate 3 with electrical components installed inside the box body 1. A number of cooling holes 4 are symmetrically opened on the two opposite side walls of the box body 1. .

[0037] Such as image 3 and Figure 4 As shown, the inner wall of the top plate of the box body 1 is fixedly connected with a soft magnet 5, and the side of the soft magnet 5 far away from the top plate of the box body 1 is attracted with a permanent magnet 6. The compression spring 7, the opposite side of the soft magnet 5 and the permanent magnet 6 are integrally formed with a boss 12, the compression spring 7 is located around the boss 12, and the side of the soft magnet 5 facing the permanent magnet 6 is fixedly connected with a guide co...

Abstract

The invention discloses a distribution box, and relates to the technical field of power equipment. The technical key points are as follows: the distribution box comprises a box body, a box door and anelectric appliance fixing plate which is installed in the box body and equipped with electric appliance elements; and a plurality of heat dissipation holes are formed in the box body. The distribution box is characterized in that the inner wall of a top plate of the box body is fixedly connected with a soft magnet; a permanent magnet is attracted to the side, away from the top plate of the box body, of the soft magnet; a compression spring in a compressed state is connected between the soft magnet and the permanent magnet; an insulating layer is arranged on the side, away from the soft magnet, of the permanent magnet; an insulating insert perpendicular to the insulating layer is arranged on the insulating layer; a left contact and a right contact which are connected with a bus are arranged below the insulating insert; and the left contact and the right contact elastically abut against each other and are symmetrically arranged with the insulating insert as a plane of symmetry. The distribution box has the advantage that the power can be cut off in time in case of fire and the risk that open fire diffuses along a wire is reduced.

Description

technical field [0001] The invention relates to the technical field of electric equipment, more specifically, it relates to a distribution box. 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 box. 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. [0003] The interior of the distribution box usually integrates many electrical component modules with high heat generation and...
