High pressure casing sensor and testing method thereof

Abstract

The invention discloses a high pressure casing sensor and a testing method thereof. The high pressure casing sensor comprises a housing and a slide block arranged in the housing, and further comprises a grounding connecting base arranged in the housing, the grounding connecting base and the housing enclose a closed ground loop, the outer side of the grounding connecting base is provided with a signal collection device, and the lower portion of the grounding connecting base is provided with a connecting device; a spring is arranged between the slide block and the grounding connecting base, and the outer side of the spring is provided with an insulating cylinder. According to the high pressure casing sensor with the structure and the testing method thereof, reliable grounding of a casing end screen is ensured by adopting the full-closed ground loop, the arranged grounding connecting base can ensure monitoring equipment safety and personal safety, meanwhile capacity of resisting disturbance is improved, the service life is prolonged, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a high-voltage bushing sensor and a test method thereof. Background technique [0002] When the bushing on-line monitoring high-frequency sensor is disassembled during the power failure inspection or test, the lead column (screw) will easily rotate, and the internal final screen grounding lead wire will easily fall off under force, resulting in the final screen cannot be reliably grounded; due to frequent disassembly, it is easy to cause metal The connecting piece is cracked and broken under force; when the transformer and bushing are treated with anti-corrosion paint during overhaul, the grounding metal connecting piece or the grounding metal soft wire cannot be effectively and reliably grounded; the small insulating porcelain sleeve is attached with anti-rust paint particles The test results have a great influence, so the test results will be inaccurate, the anti-interference a...
