Abstract
An electroscope comprises an induction electrode sensor, a signal filtering amplification unit, a small signal absolute value circuit unit, a high voltage determination unit and a signal adjusting unit. Specialties of the electroscope are that a resistor, a light emitting diode and a switch are serially connected between an anode and a cathode of a power supply. The light emitting diode is arranged at a front end in a high voltage protective cover, a lightening hole is arranged at a corresponding position at the front end of the high voltage protective cover, and the switch is arranged at a rear end of the high voltage protective cover, thereby providing convenience for controlling. When the electroscope is used for detecting a switch cabinet, a lighting device of the electroscope emits light, thereby providing convenience for operation.
Description
Technical field
The utility model belongs to the device that instructed voltage exists, particularly electroscope.
Background technology
Generally do not have lighting installation in the 10KV facility switching cabinet,,, need to change because of the voltage height damages often even lighting installation is arranged yet.There is human body electrification danger when changing the light fixture in the switch cubicle.
Summary of the invention
In order to solve the lighting problem in the switch cubicle, following technical scheme is proposed.
A kind of electroscope, it comprises the induction electrode sensor, the signal filtering amplifying unit, small-signal absolute value circuit unit, high pressure judging unit and signal conditioning unit, its special character are resistance in series, light emitting diode and switches between the both positive and negative polarity of power supply.
Light emitting diode is installed in the front end of high voltage protective cover inside, and the front end correspondence position of high voltage protective cover is offered lightening hole, and switch is installed in the rear portion of high voltage protective cover, is convenient to control.Realize the switch cubicle intraoral illumination by led lighting.
When using this electroscope that switch cubicle is carried out electrical verification, illuminating device luminous on the electroscope is convenient to operation.
The utlity model has following advantage:
Because this electroscope itself has lighting device, therefore be convenient to operation, avoid the human body electrification accident to take place.
