Embodiment Construction

[0017] like figure 1 As shown, an insulating blanket test device consists of a base [1], a cover plate [2], a pillar [3], a spring [4], and a high-voltage lead wire [5]; it is characterized in that the pillar [3] is circular , the pillar [3] is fixed on a corner of the base [1]; the size of the cover [2] is the same as that of the base [1] desktop, and the cover [2] can rotate horizontally along the pillar [3]; put it on the pillar [3] Spring [4] is arranged, and spring [4] is fixed on the cover plate [2].

[0018] like figure 2 As shown, in order to prevent the cover plate [2] from discharging on the base [1] during the test; the cover plate [2] is composed of a stainless steel plate [21] and an epoxy resin plate [22], and the stainless steel plate [21] is made of super glue Bonded on the epoxy resin plate [22]; the high-voltage lead wire [5] is connected with the stainless steel plate [21].

[0019] When conducting the insulation blanket test, the base [1] is grounded, t...

Abstract

The invention discloses an insulating mat testing device which comprises a base [1], a cover plate [2], a support pillar [3], a spring [4] and a high-voltage lead [5]. The insulating mat testing device is characterized in that the support pillar [3] is round, and is fixed in a corner of the base [1]; the size of the cover plate [2] is consistent with that of a desktop of the base [1]; the cover plate [2] can horizontally rotate along the support pillar [3]; the spring [4] sleeves the support pillar [3], and is fixed on the cover plate [2]. During an insulating mat test, the base [1] is grounded, the cover plate [2] is rotated to one side, an insulating plate is spread out on the base [1], the cover plate [2] is elevated by about 10cm, is rotated to be above the base [1] at the same time, then is lowered, and forms good contact with the insulating mat under the action of the spring [4], test voltage is applied to the high-voltage lead [5], and the cover plate [2] is rotated to be above the base after the test is finished.

Description

technical field [0001] The invention mainly relates to a test device for a live working tool, in particular to an insulating blanket test device, which can be used for the withstand voltage test of the live working tool insulating blanket. Background technique [0002] Live work in distribution network is widely used in power grid enterprises and other power supply units. Live work in distribution network can reduce the loss of power supply caused by power outage maintenance and greatly improve the reliability of power supply. The live working tools are an important material basis for ensuring the safety of people and equipment in live working in the distribution network. In order to ensure the safety and reliability of live working tools, the industry standard stipulates that live working tools for distribution network protection shall be subjected to preventive tests twice a year, with an interval of half a year. [0003] The main detection of live working tools is the in...
