Portable electrostatic voltmeter detection device

Abstract

The invention provides a portable electrostatic voltmeter detection device which comprises an outer frame, connecting shaft brackets are installed on the outer surfaces of the left end and the right end of the inner side of the outer frame, a rotating shaft is installed on the outer surface of the front side of the outer frame, monitoring blocks are arranged on the surface of the inner side of theouter frame at equal intervals, and a rotating handle is installed on the outer side surface of the lower end of the outer frame; a turntable is connected with the top of the inner end of the handle,a fixing frame is installed on the outer side of the middle of a connecting rod, the outer end of the fixing frame is connected with the inner wall of the outer frame, an extrusion plate is installedon the surface of the outer top end of a sliding plate, the inner end of the extrusion plate is connected with a supporting plate, and a clamping hole is formed in the joint of the extrusion plate and the supporting plate; a guide rod is arranged on the upper side surface of the outer end of the sliding plate, and a placing groove is reserved in the outer surface of the upper side of the supporting plate. The portable electrostatic voltmeter detection device can be conveniently carried by an operator, and raw materials with different sizes can be fixed when the portable electrostatic voltmeter detection device is used.

Description

technical field [0001] The invention relates to the technical field of voltmeters, in particular to a portable electrostatic voltmeter detection device. Background technique [0002] A voltmeter is an instrument for measuring voltage, consisting of permanent magnets, coils, etc. A voltmeter is a fairly large resistor, ideally considered to be an open circuit. An electrostatic voltmeter refers to a meter or device that uses the principle of electrostatic force to measure steady-state voltage. It can directly measure DC high voltage and AC frequency up to 1MHz. High voltage, the input impedance is extremely large and basically does not draw power from the circuit. In order to ensure that the value of the electrostatic voltmeter is more accurate, it is necessary to use a detection device to detect it. [0003] In the existing detection device, it is often impossible to disassemble itself, which is inconvenient for the operator to carry, and in the process of use, the object to...
