The connecting head combination device is used for combining a 10kV high-voltage electroscope with an insulating operating rod, and can be used for directly and conveniently inspecting high-voltage electrical equipment at a higher part on the ground by using the insulating operating rod, namely the 10kV insulating operating rod with an electroscopic function.

Background

In prior art, before and after the operation of high-voltage electrical equipment, the electricity test is needed, whether the operation is completed is determined, two insulating tools of a high-voltage electroscope and an insulating operating rod need to be carried during the operation, if the high-altitude operation is designed, after the electricity test of the electroscope is carried simultaneously, the operation of the insulating rod is time-consuming and labor-consuming, and meanwhile, personnel are easy to fatigue during high altitude, and the operation safety is influenced. The use frequency of an insulating operating rod in each operation is almost similar to that of a high-voltage electroscope, two tools supplement each other, and the operation can be completed on the same tool in order to solve the problem that the power failure and the electricity testing of the high-voltage drop-out fuse or the isolating disconnecting link and other live equipment are needed to be solved urgently.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an equipment is convenient, use nimble, safe and reliable's 10kV has the insulated operation pole of testing electric function.

The utility model adopts the technical scheme that: the 10kV insulating operating rod with the electricity testing function is characterized by comprising an L-shaped operating head, an electroscope and an insulating operating rod which are movably connected in sequence; the electroscope is internally provided with an electroscope contact, a battery and an electroscope chip which are electrically connected, and the pressure spring is sleeved on the electroscope contact; the electroscope is exposed with a display lamp and a self-checking button. It adopts split type structure, combination formula joint.

The electroscope is in threaded connection with the L-shaped operating head 1 and the insulating operating rod 8.

In order to solve the problem that the high-voltage equipment to be tested at a higher part can be conveniently tested and the problem that power failure and electricity testing are completed on the same tool, the 10kV insulating operating rod with the electricity testing function is researched. The utility model discloses have the insulating properties of traditional insulating bar or electroscope, mechanical properties and effective length's basic function, in the effective length of the insulating body of rod, connect the built-up joint and both can have the insulator spindle function, but also have the electroscope function.

According to the technical requirements and design guide rules of live working tools (GB/T18037-2000), line parts (Q/GDW 1799.2-2013) and electric power safety working rules (GB/T25318-2010) locking pin size and experiments for ball-and-socket connection of insulator string elements and the technical requirements and field practical conditions of the third edition of electric power fitting handbook (China Power publishing company, Jew), the utility model discloses should guarantee that the weight of the metal part is not more than 2kg, and the insulation length of the insulation part meets the effective insulation length requirement of 66kV:1 m. Because the R-shaped spring pin is not required to be completely pulled out, the pulling stroke length of the pin is only 4cm (adjustable allowance is reserved).

The utility model has the advantages that: 1. combine together 10kV high voltage electroscope and insulating bar, the equipment is convenient, the use is nimble, safe and reliable, has effectively solved insulating bar and high voltage electroscope device and has had the function singleness in the use, and the rate of utilization is low, shortcoming such as intensity of labour height. 2. In the effective length of the insulating rod body, the combined joint is connected, so that the insulating rod function can be realized, and the electroscope function is realized. Not only can ensure the personal safety during the work and improve the working efficiency, but also realizes the function of one rod with multiple purposes.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1-3, the part names are as follows: l type operating head 1, electroscope contact 2, compression spring 3, battery 4, display lamp 5, self-checking button 6, electroscope chip 7, insulating action bars 8, electroscope 9.

Referring to fig. 1-3, the 10kV insulating operating rod with an electricity testing function comprises an L-shaped operating head 1, an electricity tester 9 and an insulating operating rod 8 which are movably connected in sequence (the three are connected by screw threads); an electroscope contact 2, a battery 4 and an electroscope chip 7 which are electrically connected are arranged in the electroscope 9, and the pressure spring 3 is sleeved on the electroscope contact 2; the electroscope 9 is exposed with a display lamp 5 and a self-checking button 6. The electroscope 9 is connected with the L-shaped operating head 1 and the insulating operating rod 8 by screw threads. The electroscope chip 7 has model number YDQ-10.

The using method comprises the following steps: when the live equipment such as a high-voltage drop-out fuse or an isolation switch is operated to cut off power and test electricity, an electroscope 9 with an electricity testing function is assembled with the L-shaped operating head 1 and is in contact with the L-shaped operating head 1 through the pressure spring 3, so that the L-shaped operating head 1 has the electricity testing function. Before the electricity test, a self-test should be carried out, a display self-test button is pressed, and an electricity test indicator sends an intermittent oscillation sound signal to prove that the electroscope is good in performance, so that the electricity test can be carried out. When the electroscope contact contacts with the charged body, it can send out intermittent acousto-optic signal (within starting distance) to indicate that there is electricity, or if there is no intermittent acousto-optic signal, it indicates that there is no electricity. The number of the insulated operating rod 8 is judged according to the height of the equipment to be inspected, the equipment is assembled, an operator needs to keep a safe distance with the equipment to be inspected, and the insulated operating rod can be simply used as the insulated operating rod when the function of an electroscope is not needed.

Self-checking: when the self-checking button is pressed for about 1 second, the insulating rod can send out intermittent and regular audible and visual alarm signals for about 2-5 times per second, which indicates that the electroscope 9 is in a normal use state.

The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
