China High Quality overvoltage protection devices Suppliers – GD-610B Insulator Faults Detector – HV Hipot

General Information

In High Voltage Distribution Network, it usually cause the faults of flashover, grounding or porcelain explosion because of insulators degradation. So it is important to detect and eliminate the faults of insulators, to ensure safe running of transmission and distribution line.

GD-610B Insulator Faults Detector is used to locate insulator faults in power plants and substation transmission lines under uninterrupted power state. It can also be used in partial discharge detection of electrical equipment, corona discharge detection, high voltage switch discharge detection and so on.

Applications

The electric power, agricultural power, water conservancy and other departments in all regions that have power transmission lines, as well as scientific research units of industrial and mining enterprises that produce and use various high-voltage electrical equipment.

Detection items is as following

1. Unknown flashover fault of live insulators (trip and switch on for many times)
2. Composite insulator failure
3. Oxidation discharge detection of HV connectors
4. Detect discharge caused by the poor connect of the switch in HV equipment
5. Corona discharge detection
6. Pollution flashover detection

Work Principle

When the insulators in power plants and substations occurs flashover failure due to deterioration, will generate a kind of high frequency ultrasound, this high frequency ultrasound can not be heard by human ears.

The wave collector of GD-610B will receive and amplify the sound, input it to the host, using a unique micro-computer processing method, shaping, amplifying and processing this weak signal. After that, it is converted into audio signal, so that users can hear these sounds through headphones, and see the intensity indication of the sound on the LCD to judge the deterioration degree of the insulator. The instrument has strong directivity (laser locking sound source, detecting the specific location of deteriorated insulators), providing technical support for condition-based maintenance, improving work efficiency, and achieving the ultimate purpose of instrument fault detection.

Features

● Small size, light weight, novel and beautiful structure, full function, simple and fast operation, safe and reliable.
● For low or zero value insulators can automatically alarm. It is able to detect the insulator with leakage, but has not yet broken down at critical damage.
● Long-distance detection, laser aiming, accurate positioning of the deteriorated insulator and the specific location of its equipment failure, the accuracy rate is 100%.
● Dual indication of stereo headphone and LCD display, the effect is obvious.
● Strong anti-interference ability.
● High degree of intelligence:
● With data locking function.
● Under-voltage function(If low voltage, the instrument will shut off automatically).
● Constant current charging, auto stops by itself after full charge.
● Lithium-ion battery with 1000 charging times, equipped with intelligent charging system to extend battery life.
