Problems solved by technology

[0003] When electrical equipment is subjected to high-voltage test items such as lightning shock, operating wave, AC withstand voltage, and DC withstand voltage, the traditional method is to manually discharge repeatedly before and after these test items. When encountering electrical equipment with a large capacitance, discharge The time is long (this is because the large capacitance equipment test usually still has residual charge after several discharges), because the field test needs to be repeatedly discharged by manually holding the discharge rod with resistance at close range, which is not only inefficient, but also easy to cause electric shock injury. It is a serious threat to personal safety. If a long-distance remote control discharge device can be developed, it can ensure the safety of personnel and improve the efficiency of the test.

[0030] The pressure equalizing cover 9 is an elliptical structure with a smooth surface, and its function is to equalize pressure, avoiding the discharge of sharp corners and burrs from the external device; the upper and lower ends are provided with openings. The booster device 1 is firmly connected; the second is to reduce the production materials and ...

Embodiment 2

[0039] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the pressure equalizing cover 9, the connecting line 10 of the pressure equalizing cover and the support frame 15 are made of galvanized material. Installed on the support frame 15, and equipotential with the equalizing cover 9, so as to ensure that the suspended remote-controlled high-voltage test discharge grounding device is not disturbed by electromagnetic fields, and can ensure the safe operation of the high-voltage test discharge grounding device under equipotential conditions.

[0040] The pressure equalizing cover 9 is a spherical structure with a smooth appearance, and its function is to equalize pressure, avoiding the discharge of sharp corners and burrs in the external device; the upper and lower ends are provided with openings, one is convenient for hands to extend in from the upper opening to connect the pressure equalizing cover connecting line 10 with the rising The pressure equipm...

Embodiment 3

[0049] like Image 6 As shown, the specific implementation process is as follows:

[0050] After the installation and wiring of the booster device 1 is completed, install the suspended remote control high-voltage test discharge grounding device in the pressure equalizing cover 9 on the support frame 15, then fasten it on the booster device 1, and connect the voltage equalizing cover 10 Connect with step-up device 1.

[0051] The discharge grounding plate 12 is installed at the grounding position at the bottom of the booster equipment 1, the buzzer 14 is connected to the discharge grounding plate 12, and the gap of the discharge protection device 6 is adjusted according to the voltage level and test type of the equipment under test, and the discharge line is adjusted at the same time. Put device 2 positions, when making discharge wire 7 droop, magnetic force button 11 can fall in discharge ground plate 12 scopes and get final product.

[0052] In use, the test operator adjust...

Description

technical field [0001] The invention relates to a suspended remote-controlled high-voltage test discharge grounding device, in particular to a suspended remote-controlled high-voltage test discharge grounding device installed in a pressure equalizing cover. Background technique [0002] According to the requirements of Article 14.1.7 of the "Electricity Safety Work Regulations" (substation part), when changing the wiring or the end of the test, the test power supply should be disconnected and discharged first, and the high-voltage part of the booster equipment should be discharged and short-circuited to ground; Article 14.1.8 of the Safety Work Regulations (transformation part) requires that the large-capacitance equipment under test without grounding wires should be discharged before the test. Discharge to ground several times and short to ground. For safety, under normal circumstances, the discharge time is longer than the charge time. [0003] When electrical equipment ...
