Problems solved by technology

[0005] There are three major deficiencies in the traditional insulation safety tool test: 1. The test device cannot be carried to the substation for on-site testing, and it needs to go back and forth between the test workshop and the substation many times, causing certain safety hazards; 2. The test process is cumbersome and trivial. The test efficiency is not high, and the standardized test of the insulation safety equipment cannot be guaranteed; 3. The round-trip driving and handling of the safety equipment takes almost the same time as the workshop test, which seriously affects the improvement of the overall work efficiency of the safety equipment test

Embodiment 1

[0052] Example 1, power frequency withstand voltage test of insulating gloves

[0053] Test equipment: This test uses common short-tube insulating gloves with a size of 390mm×180mm×30mm (length×width×thickness), and a plastic measuring cup with a volume of 2000mL, a diameter of 120mm, and a height of 200mm is used as the internal water injection measuring cup of the insulating glove.

[0054] Test preparation: First, use the insulating glove clamp 52 to clamp the opening upper part of the insulating glove, put the insulating glove into the water storage bucket, and the water storage bucket can provide a certain support for the insulating glove. The insulating cover plate is covered 51 above the water storage bucket. At this time, the opening of the insulating glove is in a fully open state, and the tap water of 1100ml is measured with the water filling measuring cup inside the insulating glove of the present invention (aligned with the "short tube" mark on the outside of the m...

Embodiment 2

[0058] Example 2, power frequency withstand voltage test of insulating boots

[0059] Test equipment: This test uses short insulating boots with a sole length of 28cm and a width of 11cm. The grounding tray of the insulating boots on the test trolley is a stainless steel metal box of 300mm×120mm×10mm (length×width×height). The diameter of the steel balls is different. More than 4mm, the steel ball funnel box is a 2mm stainless steel plate with a length × width × height of 100mm × 100mm × 100mm, and a funnel diameter of 26mm × 26mm.

[0060] Test preparation: put a soaked sponge into the insulating boot grounding tray 10, put a metal sheet of the same size into the insulating boot for the test, and then place the insulating boot into the insulating boot grounding tray 10 filled with the soaking sponge. The steel ball bead is poured in the steel ball funnel box 14, and the steel ball falls in the insulating boot through the funnel, and covers the metal plate in the insulating bo...

Embodiment 3

[0064] Embodiment 3, power frequency withstand voltage test of insulating rod

[0065] Test equipment: the existing common 110kV voltage class insulation rod, insulation rod lifting device 6, and insulation rod fixing device 7. The insulating rod lifting device 6 is a telescopic structure including an insulating inner rod, a metal outer cylinder and a lifting rod positioning pin, wherein one insulating rod lifting device is fixed on one side of the test trolley, and the other insulating rod lifting device is provided with a pulley at the bottom , can move under the test trolley. The upper contact of the insulating rod lifting device and the test trolley is provided with a horizontal clamping device 8 to assist in adjusting the test length of the insulating rod and to ensure that the insulating rod pressurized electrode does not shift during the test. The insulating rod fixing device 7 is fixed on the top of the insulating inner rod.

Abstract

The invention relates to a portable insulation safety tool power-frequency voltage-withstand dolly, comprising a dolly portion, a clamping portion, a conductive portion, a measuring portion, and a storage portion. The portable insulation safety tool power-frequency voltage-withstand dolly can satisfy power-frequency voltage-withstand test requirements of insulating gloves, insulating boots, an insulating rods, an electroscope, a grounding wire, an insulating septum, an insulating rubber mat, and other various safety tools. The dolly saves large amount of manpower and material resources, reduces occurrence of safety accidents, and has good economical benefits and social benefits. Because of application of the test dolly, the number of times of use of the dolly to carry tools is reduced, and the dolly brings about considerable environmental benefits.

Description

technical field [0001] The invention relates to the field of electric safety, in particular to a portable insulation safety tool power frequency withstand voltage test trolley. Background technique [0002] As an important auxiliary tool to ensure personal safety, insulation safety tools are widely used in operation and maintenance personnel for switching operations, high-voltage tests, electrical isolation and other work. The "State Grid Corporation of China Electricity Safety Work Regulations" clearly requires that operators should be Use qualified insulating safety tools. [0003] Due to the large size of the existing insulating gloves / insulating boots testing machine of the team, when conducting the test of insulating safety tools and appliances, the test personnel need to go to the expired substation to retrieve the tools and appliances to the test workshop. Send them back to the substation according to the ownership and number on the tools. On the one hand, the team ...
