Abstract
The utility model discloses an electroscope for a shielded cable terminal, which comprises a telescopic handle (1), wherein the telescopic handle (1) is connected with a detecting body (2), a current detecting circuit is arranged in the detecting body (2), and a display panel (3) is arranged on the detecting body (2). The electroscope is characterized in that a metal probe (4) is in threaded connection with the front end of the detecting body (2), the length of the metal probe (4) ranges from 20 to 30cm, and the current detecting circuit is connected with the metal probe (4) and the display panel (3) respectively. The electroscope for the shielded cable terminal is simple, practical, safe, reliable and universal, and not only can be used for detecting current on the shielded cable terminal, but also can be used for detecting current on a conventional conductor.
Description
Technical field:
The utility model relates to a kind of electroscope, relates in particular to a kind of shield type cable termination electroscope, is the electroscopic device that can indicate shield type cable termination voltage whether to exist.
Background technology:
In recent years, the distribution network fast development, how controller switching equipment all insulation, hermetically sealed when improving reliability, is carried out safety practice also for the direct contact electrification of maintainer position and is brought a new difficult problem.At present, 10 kv cable feeder pillars of extensive application generally adopt the shield type cable termination, and the maintainer because internally charged body and outer shield port distance are longer, can't use conventional electroscope to carry out electrical verification after removing terminal insulation back cover.Can carry out indirect electrical verification to the equipment that can't carry out direct electrical verification.Promptly judge by the variation of signals such as the mechanical indicating positions of equipment, electric indication, charged display device, instrument and various remote measurement, remote signalling.During judgement, two and above indication should be arranged, and all indications take place simultaneously all to change, could confirm that this equipment does not have.Cable branch box only has charged display device can not judge that two and above indication take place simultaneously to change, can't carry out indirect electrical verification.To maintainer bring great security risk if blindly install ground wire this moment.
The utility model content:
The purpose of this utility model be to overcome the deficiency of above-mentioned prior art and provide a kind of simple and practical, safe and reliable, have a versatility, can electrical verification on the shield type cable termination, shield type cable termination electroscope that also can electrical verification on conventional conductor.
The purpose of this utility model can reach by following measure: a kind of shield type cable termination electroscope, it has telescoping handle, telescoping handle joint detection body, detect in the body and be provided with electrical circuit inspection, detect body and be provided with display panel, the front end that it is characterized in that the detecting body metal probe that is threaded, the length of metal probe is 20cm-30cm, electrical circuit inspection connects metal probe and display panel respectively.
The utility model can produce following good effect compared with the prior art: the utility model extends to 20cm-30cm with electrical verification front end metal probe, satisfy the needs of the direct electrical verification of shield type cable termination fully, simple and practical, safe and reliable, have a versatility, can electrical verification on the shield type cable termination, also can electrical verification on conventional conductor, and identify can be with ground wire by the terminal residual charge that bleed off cable of electroscope probe behind the true no-voltage.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment: embodiment of the present utility model is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of shield type cable termination electroscope (referring to accompanying drawing), it has telescoping handle 1, telescoping handle 1 joint detection body 2, detect body 2 and be provided with display panel 3, the front end that detects body 2 metal probe 4 that is threaded, detect in the body 2 and be provided with electrical circuit inspection, electrical circuit inspection connects metal probe 4 and display panel 3 respectively.The length of metal probe 4 is 20cm-30cm, and during use, metal probe 4 stretches in cable ring-system cabinet and the feeder pillar shield type cable termination is carried out electrical verification, and simultaneously, metal probe 4 rearward end ground wires can bleed off the residual charge of cable.
