Problems solved by technology

However, in actual use, since the drop fuse is fixedly installed on the distribution transformer, the terminal lugs cannot be adjusted, so there are angles that do not correspond, the connection is not flexible, the installation is troublesome, and it can only be used for electrical testing and grounding. Cables cannot be connected at the lower end o

Abstract

The invention discloses a regulation connection type electricity testing grounding ring which comprises a ring and a straight bar, wherein the ring and the straight bar are made of conductor materials, an insulation sheath is arranged outside the ring and the straight bar, the head of the straight bar is connected with a terminal A, and one end of the ring is provided with a grounding dew cell. The regulation connection type electricity testing grounding ring is characterized in that the terminal A is movably connected with an angle regulation plate, a hanging hole is manufactured on the angle regulation plate and is connected with a dropping fuse, the bottom of the ring is connected with a terminal B, and the terminal B is connected with a 10KV three-phase cable or a downlead of a distribution transformer. The product is used for electricity testing grounding and connecting a whole line with a branch line or a user cable. The terminal A is movably connected with the angle regulation plate with flexible and convenient installation. The bottom of the ring is connected with the terminal B, and the 10KV three-phase cable or the distribution transformer can be connected under the condition that a power supply line is not in power cut.

Description

technical field [0001] The invention relates to both cable connection and electrical testing grounding, in particular to a connection-type electrical testing grounding ring whose angle can be adjusted to facilitate installation. Background technique [0002] When high-voltage cables and distribution transformers are operated, the power supply needs to be cut off. The existing technology does not carry out electrical inspection (voltage and current test) after the power supply is cut off, and there is no grounding point, which belongs to prohibited operations and involves personal safety issues. Therefore, the applicant once designed a "10KV cable, distribution transformer grounding copper ring", Chinese patent number ZL200620102231.4, its structure includes a copper ring with a ring and a straight rod, an iron core is installed in the copper ring, a copper There is an insulating sheath outside the ring, and the head of the copper ring is connected to a terminal, which is con...
