Abstract

The invention provides a low-voltage insulation sheath. The low-voltage insulation sheath comprises a clamping part and an operating part, wherein the clamping part is provided with a line through gap and a clamping cavity, the clamping cavity communicates with the line through gap, the clamping part is made of insulation material, and the operating part is connected with the clamping part so that the line through gap is opened or closed. With the adoption of the technical scheme, a metal contact is only needed to be stored in the low-voltage insulation sheath when live-line low-voltage operation is performed by a worker by arranging the special low-voltage insulation sheath, so that contact short-circuit among metal contacts can be effectively prevented, and the low-voltage insulation sheath has the advantages of time and labor saving and is easy to operate. The insulation property of the low-voltage insulation sheath can be ensured, and a potential risk is eliminated.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a low-voltage insulating sheath. Background technique [0002] With the widespread application of high-power household appliances such as electric heating, the low-voltage equipment of power companies is under the test of high current. [0003] In low-voltage repair accidents, there are a large number of damages to meters, household wires, isolating switches, miniature circuit breakers and other equipment due to high current heating. In the process of disassembling and installing these devices, due to the short distance between different phase lines, the exposed metal contacts are easily short-circuited due to contact, which seriously threatens the safety of operators. [0004] At present, the commonly used method is to wrap the metal contacts with insulating tape to ensure that no short circuit occurs. This requires the insulation tape to be removed after the equipment...
