200KHz Partial Discharge Detector For Switchgear

ZXPD-100K Partial Discharge Detector For Switchgear

The product, with a portable structure and embedded signal receiving and data processing module, has multiple analysis modes and can conveniently measure the UHF signals and the ultrasonic signals generated by the partial discharge of the electric equipment. Compared with similar products, this product has convenient operation and strong function.

Features

1. Applicable scope: the non-intrusive mode is adopted to detect and locate the partial discharge defects of the high-voltage electric equipment.

2. sensor configuration

Standard: UA, TEV

Optional: Sensor network for transformer, the high-frequency sensor for GIS, the sensor for high-voltage cable, or other senors customized according to user's requirements.

3. Detection principle: UHF (Ultra High Frequency) method, UA (Ultrasonic Analysis) method, and TEV (Transient Earth Voltage) method.

Technical Indicators

1. Detection frequency band:

UA: 40～200KHz

TEV: 3~100MHz

UHF: 300～2000MHz.

2. Measurement range:

UA: -90～80dB

TEV: -80～10dBm

UHF: -80～10dBm.

3. Sensitivity: the minimum sensitivity is 10pC (specifically determined by the distance between the sensor and the discharge source).

4. Sensor:

a) Ultrasonic sensor: 20～200(kHz);

b) EV (Transient Earth Voltage) sensor: 5 ~ 100MHz;

c) UHF sensor: 300～2000(MHz), with directional reception characteristic.

5. Embedded ultrasonic sensor and TEV & UA integrated sensor: such components as transformer dedicated sensor, GIS dedicated sensor, and cable dedicated sensor can be selected;

6. Software function:

a) Continuously detect UHF, TEV, and ultrasonic signals to judge whether there is any partial discharge;

b) Display the variation tendency of the detected signal in a real-time manner to intuitionally judge the development of the partial discharge signal;

c) Field data storage function;

7. Instrument characteristics:

a) Screen display: high-contrast 3.5”TFT color screen.

b) Data storage: 1000 groups of test data can be stored.

c) Working power supply: embedded 8.4V lithium battery for 8h’s continuous operation.

d) Power supply: input 100-240VAC, output 8.4V/3A, charging time 3～4h.

e) Boundary dimension: 220 * 100 * 40.

f) Instrument weight: 1.5kg.

g) Environment temperature: -25℃～45℃.

h) Storage temperature: -35℃～60℃.

8. Complete configuration: host machine, sensor, AC adapter, connecting cable, and transport case.
