Abstract

The utility model relates to a safety detection tool for a high-voltage AC (alternating current) circuit and equipment, in particular to a charging type electroscope. The present electroscope cannot well solve problems that an oxidized and rusted primary cell causes poor contact, the normal use of the electroscope is influenced, and the personal life safety is threatened. In the utility model, a cell circuit output terminal is connected with a high-voltage detection circuit input terminal, a high-voltage detection circuit output terminal is electrically connected with a high-voltage detection voice alarming circuit input terminal and a high-voltage detection light alarming circuit input terminal, a rechargeable cell is welded on a cell circuit, and potential safety hazards are well eliminated.

Description

Rechargeable electroscope

Technical field

The utility model relates to the safety detection instrument of high-voltage alternating circuit and equipment, particularly a kind of rechargeable electroscope.

Background technology

In the electric system, many working environments all exist a lot of potential safety hazards, especially set up in the working environment that maintenance and high-tension apparatus safeguard at high-tension bus-bar, and can fast and effeciently checking out working environment, safety and people's life be closely bound up.The high-voltage alternating electroscope is as a kind of electroscopy equipment, well solved the detection problem of high pressure circumstances not known, but because its environment for use usually is the sleet humidity, existing electroscope can not be got rid of the disposable battery oxidation and rusting well and cause loose contact, influencing electroscope normally uses, threat personnel life security problem, its function indication is also perfect not to the utmost in addition.

The utility model content

The utility model purpose provides a kind of safer reliable, the rechargeable electroscope of perfect in shape and function.

Technical solutions of the utility model: a kind of rechargeable electroscope, its battery circuit output terminal is connected with the high-voltage detecting circuit input end, the high-voltage detecting circuit output terminal detects the audible alarm circuit input end with high pressure simultaneously, high pressure detects the optical alarm circuit input end and is electrically connected, and is electrically connected rechargeable battery on the battery circuit.

Rechargeable battery on the battery circuit is a lithium battery, and it is welded on the battery circuit.

The battery circuit output terminal is electrically connected the under-voltage indicating circuit of battery.

The utility model solved disposable battery out of doors wet environment or long-time use the surface easily oxidation and rusting cause loose contact, influence the normal shortcoming of using of electroscope, charged lithium cells is welded on the disposable battery that has replaced the needs replacing to install on the battery circuit plate, has got rid of potential safety hazard well; Designed the under-voltage indication of low-power consumption in the battery under-voltage condition, still can operate as normal 1-2 hour after under-voltage indication occurs, solved the problem that can not in time charge out of doors but still can use.

Description of drawings

Accompanying drawing is the utility model block diagram.

Embodiment

The utility model welds charged lithium cells and has replaced needs to change the disposable battery of installing on the battery circuit plate, avoid existing electroscope can not get rid of the disposable battery oxidation and rusting well and caused loose contact, influence electroscope and normally use, threaten the major safety problems of personnel's life security.

Be electrically connected the under-voltage indicating circuit of battery (common circuit) at the battery circuit output terminal, prompting staff cell voltage descends, but it still can operate as normal 1-2 hour after under-voltage indication occurs.

Used high pressure to detect antenna in the utility model high-voltage detecting circuit, high pressure detects in the audible alarm circuit and has used hummer, and high pressure detects in optical alarm circuit, the under-voltage indicating circuit of battery and used pilot lamp.
