Embodiment Construction

[0017] Specific implementation

[0018] A kind of non-contact intelligent high-voltage DC electroscope figure 1 , It consists of a handheld pole, a detector, and a distance measuring system. The detector consists of a housing 1, a rotary switch 2, a high-brightness LED indicator 3, a digital display 4, a buzzer 5, a built-in circuit, a DC detection sensor, etc. (see figure 1 ), the built-in circuit is composed of A / D module circuit, rectifier and step-down circuit, single-chip circuit, self-check circuit, power module, etc. The power supply 5V voltage is used to drive the single-chip circuit (see image 3 ), a handheld pole is installed under the detector.

[0019] in image 3 In the illustrated embodiment, a single-chip microcomputer circuit is used to implement voltage measurement, display, and alarm prompt functions. The single-chip microcomputer samples the voltage on the DC detection sensor through the A / D sampling module circuit, and the direct-current single-chip microcomput...

Abstract

The invention belongs to the technical field of electric power engineering appliances, and especially relates to a non-contact intelligent high-voltage direct-current electroscope. The electroscope ismainly composed of a detector, a hand-held rod and a range finding system. The detector is composed of a housing 1, a turn button switch 2, a high brightness LED indicating lamp 3, a digital displayscreen 4, a buzzer 5, a built-in circuit, a direct-current detection sensor, etc. The built-in circuit is composed of an A / D module circuit, a rectification, filtering and voltage drop circuit, a single-chip microcomputer circuit, a self-check circuit, a power supply module, etc. A power supply 5V voltage is used for driving the single-chip microcomputer circuit. The hand-held rod is arranged below the detector. The power supply 5V voltage is used for driving the single-chip microcomputer circuit. Analog signals in the direct-current detection sensor are converted into digital signals throughAD collection, a result is displayed on the LCD display screen through single-chip microcomputer processing, and acousto-optic alarm signals are emitted. The direct-current detection sensor is composed of a rotor shield sheet 6, a stator sensing sheet 7, a bearing 9 and a direct-current motor 8.

Description

Technical field [0001] The invention belongs to the technical field of electrical engineering appliances, and particularly relates to a non-contact intelligent high-voltage DC electroscope. Background technique [0002] With the continuous improvement of the operating voltage level of DC transmission projects, the difficulty of line maintenance has gradually increased, and the requirements for operation and maintenance of safety tools and equipment have gradually increased. However, at present, some of the safety tools and equipment in my country's DC transmission projects are still in an underdeveloped stage, and some safety tools and equipment cannot meet the needs of line maintenance. This undoubtedly increases the difficulty of grid operation and maintenance and increases the labor intensity of staff. [0003] At present, the existing electrical inspection methods and testing tools for DC transmission equipment in our country are relatively backward. The operators wear a full s...
