Abstract

A V-type heating sheet comprises a thermal insulation slab, the upper surface of the thermal insulation slab is provided with a heating sheet body in a V shape, the upper surface of the thermal insulation slab is connected with the two ends of the V-shaped heating sheet body, the heating sheet body is sleeved with an insulation sleeve, and a plurality of magnets are arranged on the lower surface of the thermal insulation slab. The insulation sleeve is arranged on the periphery of the heating sheet body of the V-type heating sheet and can prevent the heating sheet from leaking electricity, and low-voltage electric shock risks are effectively avoided in the replacement and maintenance processes of the V-type heating sheet. The heating sheet body can attract the side wall of a transformer substation through the magnets arranged on the lower surface of the thermal insulation slab to achieve fixation of the V-type heating sheet, so that the arrangement of the V-type heating sheet is not limited by the space in the transformer substation, and the arrangement range of the V-type heating sheet is enlarged.

Description

technical field [0001] The invention relates to a heating chip, in particular to a V-shaped heating chip. Background technique [0002] V-shaped heating sheet is a form of electric energy utilization that converts electrical energy into thermal energy to heat objects. The outer periphery of the main body of the existing V-shaped heater does not have an insulating sleeve, and the operator has a low-voltage electric shock hazard during the replacement and maintenance of the V-shaped heater, which increases the difficulty and cost of replacing and maintaining the V-shaped heater. The existing V-shaped heaters can only be fixed by nuts. During installation, through holes need to be opened on the side wall of the substation. The installation time is long, and the space in the substation is small. It is difficult to use tools such as wrenches, which limits the installation of V-shaped heaters. scope. Contents of the invention [0003] The purpose of the present invention is to...
