Abstract

The invention relates to a non-contact type intelligent high-voltage electroscope capable of measuring a voltage value. The non-contact type intelligent high-voltage electroscope is used in power transmission line electrical inspection operation, and belongs to the field of electrical tools and appliances. The non-contact type intelligent high-voltage electroscope comprises a detection instrument, a handheld rod, a range finding system and a control module, wherein the detection instrument is composed of a shell body 1, a built-in circuit, a knob switch 2, an electromagnetic field sensor, a high-brightness LED indication lamp 4, a wireless transmitting unit 3 and the like; and the control module is composed of a single chip microcomputer control circuit, an LCD screen 6, a wireless receiving unit 7, switching buttons 10, an audible alarm 9 and high-brightness LED indication lamps 8. The non-contact type intelligent high-voltage electroscope is capable of non-contact electrical inspection at a long distance, can distinguish an induced voltage and a working voltage of a maintenance line, can calculate and display a voltage value of the line, and has advantages of being reliable in electrical inspection, safe in operation, digitalized and the like.

Description

technical field [0001] The invention belongs to the technical field of electric engineering appliances, in particular to a non-contact intelligent high-voltage electroscope with measurable voltage value. Background technique [0002] A variety of high-voltage equipment is widely used in the power system, especially whether the high-voltage equipment is charged or not directly affects the personal safety of the operator. Electrical appliances play an extremely important role in the safe production of the power industry. [0003] The problems faced by line maintenance are as follows: First, when one power supply circuit is powered off and the adjacent circuit is powered normally, there is an induced voltage as high as 45% of the working voltage on the power-off circuit. The second is that when the dual-circuit power supply is disconnected, the power supply will be sent back to the broken line, and the faulty line will have a working voltage. The current high-voltage electros...
