Problems solved by technology

[0002] When the staff inspect some power distribution equipment on a daily basis, due to the interference of external noise, it is difficult to directly judge whether the operation of the power distribution equipment is normal through the ear during the inspection process, resulting in a long inspection time for the inspectors, which cannot guarantee the inspection of the inspectors At the same time, it is easy to get an electric shock when touching the power distribution equipment during the inspection process, which seriously affects the personal safety of the inspectors

Embodiment

[0017] As a preferred example, when the person on duty patrols power distribution equipment such as transformers, he can carry this device with him. When patrolling, he presses the sound collecting head 1 on the transformer, and the sound collecting head 1 collects the sound, and the hollow tube 2 can conduct the sound. The principle is that the sound will be transmitted to the hollow tube 2. The hollow tube 2 is composed of 6 sections, and the length of each section is 25cm. When each section is closed, the sound collecting head 1 and the hollow tube 2 are made of high-voltage insulating materials, so there is no need to worry about the risk of electric shock. The hollow tube 2 is connected with a flexible conduit 3, which can be made of rubber and other materials. Flexible conduit 3, flexible conduit 3 It is connected with the listening head 5 through the tee 4. The listening head 5 has two bifurcated ends, corresponding to the left ear and the right ear respectively. The lis...

Abstract

The invention discloses a sound insulation listening rod for distribution equipment, belonging to the technical field of electrical product accessories. The sound insulation listening rod for the distribution equipment comprises a listening rod body, wherein the listening rod body comprises a hollow pipe; one end of the hollow pipe is connected with a sound collecting head; the other end of the hollow pipe is connected with a flexible conduit; the other end of the flexible conduit is connected with a listening head with two forky ends by a tee joint; an earplug is arranged on the listening head; the hollow pipe is of pumping rod tube type, comprises at least two sections, is capable of expending and retracting freely, and the sound collecting head and the hollow pipe are made from high-pressure insulating materials. The sound insulation listening rod for the distribution equipment can be taken along, and the problems that whether the transformer operation has malfunction and the like can be resolved and judged; the sound insulation listening rod for the distribution equipment is suitable for a noisy work environment, meanwhile the occurrence of an electric shock hazard can be prevented; the patrol time of a worker is shortened, the quality of work is improved, and the sound insulation listening rod for the distribution equipment can be widely used in checking the malfunction problems of the distribution equipment such as a transformer.

Description

technical field [0001] The invention relates to a listening stick, in particular to a sound-insulating listening stick for power distribution equipment, which belongs to the technical field of electrical product accessories. Background technique [0002] When the staff inspect some power distribution equipment on a daily basis, due to the interference of external noise, it is difficult to directly judge whether the operation of the power distribution equipment is normal through the ear during the inspection process, resulting in a long inspection time for the inspectors, which cannot guarantee the inspection of the inspectors At the same time, it is easy to get an electric shock when touching the power distribution equipment during the inspection process, which seriously affects the personal safety of the inspectors. Therefore, it is necessary to develop a listening device capable of effectively isolating external noise and having a clear hearing effect, so as to solve probl...
