YGSY contact and non-contact type combination electroscope

Overview
 
Contact and non-contact type combination electroscope (YGSY) is our new patented product. This product has double electricity inspection modes, which are contact electricity inspection and non-contact electricity inspection respectively. Each mode has its own battery and circuit, this ensures that when one circuit is underpowered, it does not affect the normal operation of the other circuit. This product has improved accuracy of electricity inspection result through double electricity inspection and further guaranteed safety of the operator. This product is packaged in exquisite black PU and can be attached to belt. It is easy to carry. The head of the electroscope is collapsible, so the volume is small and it is easy to transport.







Product function profile
 
1 Contact electroscope part: A set of 50Hz sine wave power frequency AC signal generator circuit is added in the electroscope. When self-check button is pressed, self-check function range from starting power supply, sound-light alarm, DC driver circuit to AC exploring electrode, it simulates the working state of starting the electroscope under low-voltage signal with power frequency. This realizes a whole set of whole circuit self-detection function, so it guarantees the reliability of self-detection function, furthermore, it greatly improves the effective and accurate performance of electroscope.

 
2 Non-contact electroscope part: When the electroscope close to a live line, the electroscope carries out front-end analysis and process of the received detection signal, takes out 50Hz power frequency signal, eliminate interference signals by digital filtering, analyze its signal strength, send a wireless alarm signal to the receiving terminal when the signal strength reaches the preset value, the receiving terminal gives an alarm after receiving the signal, prompts users that the line is charged and please pay attention to safety. The warning system only gives a voltage warning of 50-60Hz power frequency. The circuit resists interference by digital filtering which is stable and reliable. Special remark: non-contact electroscope cannot give a warning for DC, high frequency and static.
