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 trivi

Example Embodiment

[0052] Example 1: Power frequency withstand voltage test of insulated gloves

[0053] Test equipment: In this test, a short cylindrical insulated glove with a common size of 390mm×180mm×30mm (length×width×thickness) is used, and a plastic measuring cup with a volume of 2000mL, a diameter of 120mm and a height of 200mm is used as the water injection measuring cup inside the insulated glove.

[0054] Test preparation: firstly, clamp the upper part of the opening of the insulating glove with the insulating glove clamp 52, and put the insulating glove into a water storage bucket, which can provide a certain support for the insulating glove. Cover 51 with an insulating cover plate above the water storage bucket. At this time, the opening of the insulated glove is completely open. Use the water-filling measuring cup inside the insulated glove of the present invention to measure 1100ml of tap water (aligned with the "short tube" mark on the outside of the measuring cup) and pour it into t...

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

[0059] Test equipment: This test uses short-tube insulated boots with a sole length of 28cm and a width of 11cm. The grounding tray of the insulated shoe on the test cart is a stainless steel metal box of 300mm×120mm×10mm (length×width×height). The diameter of the steel ball is different. Larger 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 water-immersed sponge into the grounding tray 10 of the insulating shoe, and put a metal piece equivalent to the size of the insulating shoe for the test, and then place the insulating shoe in the grounding tray 10 of the insulating shoe with the water-immersed sponge. The small steel ball is poured into the steel ball funnel box 14, the steel ball falls into the insulating shoe through the funnel, and covers the metal plate in t...

Example Embodiment

[0064] Example three, power frequency withstand voltage test of insulating rod

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

[0066] Test preparation: pass the insulating rods through the m...

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 ...
