Abstract
The invention provides a 10kV cable electroscope, which comprises an electroscope body, and an electroscopic head which is a telescopic metal rod, the structure thereof is composed of a plurality of pipe joints; a lower part of a former pipe joint of two adjacent pipe joints is inserted in an upper part of the next pipe joint to form the clearance fit, a lower end of the last pipe joint is fixed at a top part of the electroscope body, an upper part of the headmost pipe joint is inserted in and fixed with a solid metal rod. The 10kV cable electroscope is simple in structure, convenient and practical, which especially can meet a demand of performing the electroscopy operation to a narrow position in a ring main unit and a cable branch box.
Description
Technical field
Whether charged the present invention relates to inspection machine instrument, be high voltage electroscope specifically.
Background technology
The distribution network systems of electric system generally adopts the ring main unit and the cable branch box (as sharp Automation Co., Ltd of Beijing section) of production, and some load transition head outsides are insulators, and the nonisulated body that has only electroscope to touch the inside just can carry out the electrical verification operation.And existing electroscope contact generally all has only 10 centimeter length, effective contact electrification body, thus electrical verification work brings the trouble of many difficulties, has increased the unsafe factor in producing.
Summary of the invention
The purpose of this invention is to provide a kind of simple and practical, electrical verification position unrestricted 10kV cable electroscope.
The object of the present invention is achieved like this: a kind of 10kV cable electroscope, comprise the electroscope body, the electrical verification head, the electrical verification head is a telescopic Metallic rod, its structure is: be made up of a plurality of tube couplings, in these a plurality of tube couplings, the bottom of the last tube coupling of adjacent two tube couplings is inserted the top of back one tube coupling and is formed movingly, the lower end of last tube coupling is fixed on described electroscope bodies top, and a solid metal is inserted and is fixed with on the top of previous tube coupling.
Also be provided with the position-limit mechanism that prevents to deviate between above-mentioned adjacent two tube couplings: the back one tube coupling internal face on a hole is arranged, the hole internal fixation has stage clip, is connected with steel ball above the stage clip, have on the outside wall surface of last tube coupling one with the suitable arc shrinkage pool of steel ball.
Above-mentioned telescopic Metallic rod is made up of 4 tube couplings.
The invention has the beneficial effects as follows:
Electroscope of the present invention is simple in structure, and is convenient and practical, not limited by the electrical verification position.The head of electroscope is designed to a telescopic Metallic rod.As existing retractable antenna.During electrical verification, only the Metallic rod elongation just can need be met the demands.On original electroscope basis, the Metallic rod that only needs Metallic rod to be changed to extension type promptly can meet the demands.Especially can satisfy the demand that the position narrow positions is carried out electrical verification work in existing ring main unit and the cable branch box.
Description of drawings
Fig. 1 is the structural drawing of electrical verification head.
Fig. 2 is the synoptic diagram that position-limit mechanism is set between forward and backward two tube couplings shown in Figure 1.
Embodiment
Fig. 1 illustrates, the present invention includes the electroscope body, the electrical verification head, the electrical verification head is a telescopic Metallic rod, its structure is: be made up of a plurality of tube couplings, in these a plurality of tube couplings, the bottom of the last tube coupling 1c of adjacent two tube couplings is inserted the top of back one tube coupling 1b and is formed movingly, the lower end of last tube coupling 1a is fixed on described electroscope bodies top, and a solid metal 1e is inserted and is fixed with on the top of the most previous tube coupling 1d.Referring to Fig. 2, also be provided with the position-limit mechanism that prevents to deviate between adjacent two tube couplings: on the internal face of back one tube coupling 1b a hole is arranged, the hole internal fixation has stage clip 3, is connected with steel ball 2 above the stage clip 3, have on the outside wall surface of last tube coupling 1c one with the suitable arc shrinkage pool 4 of steel ball 2.Telescopic Metallic rod is formed (as shown in Figure 1) by 4 tube couplings.
Claims (3)
1. 10kV cable electroscope, comprise, the electroscope body, the electrical verification head is characterized in that: described electrical verification head is a telescopic Metallic rod, and its structure is: be made up of a plurality of tube couplings, in these a plurality of tube couplings, the bottom of the last tube couplings of adjacent two tube couplings (1c) is inserted the top of back one tube coupling (1b) and is formed movingly, and the lower end of last tube coupling (1a) is fixed on described electroscope bodies top, and a solid metal (1e) is inserted and is fixed with on the top of the most previous tube coupling (1d).
