Insulation shielding cover for electric power detection

Abstract

The invention provides an insulation shielding cover for electric power detection. The insulation shielding cover is used for shielding a cross arm for live working and comprises a cross arm cover body, two wire fixing mechanisms, an insulation baffle plate and a detection device, wherein the cross arm cover body includes a first body and a second body; the two wire fixing mechanisms are respectively, oppositely and fixedly disposed on an outer wall of the first body; the insulation baffle plate includes two fan-shaped plate bodies which are located on the same plane; and the detection device includes an alarm, a voltage acquisition module which is disposed inside a groove, and a controller which is electrically connected with the alarm and the voltage acquisition module. According to the insulation shielding cover, a second body is slidably disposed in the first body in a sleeved manner, the second body can be stretched out and drawn back in the first body, the length of the shielding cover is adjusted according to the length of the cross arm so that a single shielding cover can be suitable for cross arms of various sizes; meanwhile as the detection device is disposed, the magnitude of voltage borne by the cross arm is detected at any time; and when the magnitude of voltage exceeds the safety value borne by a human body, an alarm device gives an alarm in time, thereby improving the safety of the shielding cover.

Description

technical field [0001] The invention relates to the field of electric power detection and maintenance equipment. More specifically, the present invention relates to an insulating shield for electric power detection. Background technique [0002] In order to ensure the safety and stability of the grid power supply, it is necessary to regularly inspect and modify the power equipment. Most of them are live work at high altitudes. device. In the prior art, insulating blankets and shielding covers are often used to cover the cross-arm. However, due to the special shape of the cross-arm, the process of wrapping the blanket with the insulating blanket is time-consuming and laborious, and the appearance after wrapping is not neat. The corner burrs are easy to damage the insulating blanket, which brings safety hazards to live work; the size and structure of the existing shielding cover are relatively fixed, and the size cannot be adjusted, while the cross-arm has different sizes, w...

In the prior art, insulating blankets and shielding covers are often used to cover the cross-arm. However, due to the special shape of the cross-arm, the process of wrapping the blanket with the insulating blanket is time-consuming and laborious, and the appearance after wrapping is not neat. During the wrapping process, due to the iron attachment of the cross-arm The corner burrs are easy to damage the insulating blanket, which brings safety hazards to live work; the size and structure of the existing shielding cover are relatively fixed, and the size cannot be adjusted, and the cross-arm has different sizes, which limits the scope of use of a single shielding cover. The function of the cover is relatively simple, and it does not have the function of checking the voltage or current value of the cross-arm and reminding the operator in time
