Cable connection box for power supply cable

Abstract

The invention relates to the technical field of cable connection boxes, in particular to a cable connection box for a power supply cable. The cable connection box comprises a main body mechanism, wherein a limiting mechanism slides on the main body mechanism; a driving mechanism is rotationally arranged on the main body mechanism in a matched manner; a linkage mechanism is fixedly mounted on the driving mechanism; the driving mechanism is connected with an abutting mechanism; and a cleaning mechanism is installed on the abutting mechanism in a matched mode. Before the interior of the connection box is overhauled, the limiting mechanism is shifted by hand, so the limiting mechanism slides out of the main body mechanism when sliding, the connection box is opened conveniently, and the interior of the connection box is sealed conveniently to be prevented from being affected with damp; and when the connection box is opened, an operator can rotate the driving mechanism with hands, then the driving mechanism drives the linkage mechanism to rotate, then the abutting mechanism slides out of the interior of the main body mechanism and abuts against the box door of the connection box, and therefore, the situation that the operator is hit by the box door when the box door rotates down in the overhauling process of the operator is prevented.

Description

technical field [0001] The invention relates to the technical field of cable connection boxes, in particular to a cable connection box for power supply cables. Background technique [0002] The cable connection box is a kind of equipment used for branching, branching, connecting and converting circuits on cable lines, most of which are used outdoors. In the power system, it is often necessary to carry out field tests on large-scale power equipment, such as AC withstand voltage tests of circuit breakers, ground grid impedance tests and other tests. These large-scale high-voltage tests often require a larger capacity power supply, and some test power supplies even require hundreds of KVA can meet the requirements. At this time, the cables that can undertake the power connection task are limited by the current carrying capacity, and cables with larger cross-sectional areas need to be used to meet the current requirements in the test. [0003] However, during the use of cable c...

Problems solved by technology

[0003] However, during the use of cable connection boxes, some connection boxes are installed outdoors. When encountering floods or rain and snow environments, due to the poor sealing effect between the connection box and the box door, when the inside of the connection box is damp There are likely to be potential safety hazards; in addition, when the interior of the cable is overhauled or the cable is connected or removed, the internal components will become loose due to the long-term rotation of the box door, and the operator may be rotated during the overhaul process, thereby injuring the operator. While there are certain potential safety hazards, it is also not conducive to improving the maintenance efficiency of operators.
