Abstract

The invention discloses a multipurpose grounding device. The device comprises a first box body, a second box body and a third box body which are connected in sequence, wherein a first automatic winderis arranged in the first box body, a power strip is arranged on the second box body, a plurality of sockets are arranged on the power strip, power is supplied to the sockets through power lines, a plurality of circuit switching assemblies are arranged in the third box body, and each circuit switching assembly comprises a second automatic winder and a third automatic winder of which the wiring ends are connected in series. According to the invention, the first wiring end of the first automatic winder is the free end, the electric wire can be lengthened, a long-distance electric appliance powerconnection test is facilitated, and meanwhile, cable winding and unwinding are easy and rapid; the arrangement of the jointing clamp facilitates rapid electric connection with a to-be-tested electricappliance; the power strip embedded in the second box body plays a role in supplying power; the circuit switching assemblies which are disposed in the third box body are used for the electric connection between different electric appliances. According to the invention, cable take-up and pay-off are simple and rapid, a line connection effect is achieved, and various on-site requirements can be met.

Description

technical field [0001] The invention relates to a grounding box in the field of cable transmission, in particular to a multipurpose grounding device. Background technique [0002] Electric lines are transported by cables on a large scale, and the cable grounding box is an important part of the transmission cable system in the power industry. It is widely used in projects such as electric power, railways, urban construction, water conservancy, and rail transit. The grounding box is used for The place where the grounding wire is placed plays the role of protecting the grounding wire. It is specifically divided into a direct grounding box, a protective grounding box, a three-phase cross-connected grounding box, and a three-phase six-wire grounding box. [0003] However, the existing grounding box has the following problems: 1. At present, the method of winding the grounding wire on the grounding insulating rod is generally used to complete the winding. , easy to damage the wir...
