Abstract
The utility model provides a grounding electricity testing indicating device, relates to an auxiliary device of power supply and distribution devices, and especially belongs to an indicating device which can indicate whether a power supply and distribution is charged. The grounding electricity testing indicating device comprises a fixing and mounting device, a current transformer (1), and a lamp indicating device (3). The device is characterized in that the fixing and mounting device is an elastic clamp (2) used to clamp a wire, and the lamp indicating device is formed by a rectification circuit and an illuminant neon bulb. An input end of the rectification circuit is connected with a secondary coil of a current transformer, and an output end of the rectification circuit is connected with a capacitor and the illuminant neon bulb in parallel. The grounding electricity testing indicating device has positive effects of simple structure, easy judgment, and is striking and intuitive.
Description
Technical field
The utility model relates to a kind of power supplying and distributing equipment auxiliary equipment, particularly belongs to a kind of and can indicate whether charged indicating device of power and distribution supply cable.
Background technology
For guaranteeing staff's personal safety, when the installing ground wire, need to implement outage to corresponding power and distribution supply cable.For preventing because human negligence causes the generation of forgetting powering-off state, often needing the special messenger to step on the bar electrical verification, not only operation is loaded down with trivial details, and namely there is potential safety hazard in itself in advance.
The utility model content
The purpose of this utility model namely is to provide a kind of novel ground connection electrical verification indicating device, the purpose that simplify working routine to reach, reduces potential safety hazard.
Ground connection electrical verification indicating device provided by the utility model comprises secure mounting arrangements summation current transformer, the aobvious device of lamp, it is characterized in that, described secure mounting arrangements is the elastic clip that holds wire; The aobvious device of described lamp is made of rectification circuit, luminous neon bulb, and rectification circuit input end is connected with the current transformer secondary coil, and the output terminal of rectification circuit connects electric capacity and luminous neon bulb with parallel way.
When wire has electric current to pass through, produce magnetic field, current transformer secondary coil generation current is capacitor charging by rectification circuit, when the electric capacity both end voltage is raised to the neon bulb limiting voltage, the neon bulb conducting is luminous, and capacitor discharge recharges, go round and begin again, the neon bulb flashing, this circuit of prompting staff is charged, has simple in structure, eye-catching good effect directly perceived, that easily judge.
