JNC-kerui has outstanding technical researching team and superior equipments, specially concentrate on research & development, production, sales and service of neutral grounding series products of power distribution system. The transformer neutral grounding resistance cabinet we developed and produced is applicable to 6~35KV power distribution grid of cable running lines in cities, large industrial enterprises, factories, airports, seaports, subway and etc. as well as 0.66KV system in mine digging and 0.4kv/6kv/10kv system in power plants.

Typical Technology Parameters Of The Product

Can design different kinds of resistors basing on the user requirements,resistance is from 1Ωto 2000Ω,the flowing current ia allowed from Ω~2000Ω,and the flowing time is 10s,15s,30s,60s,2h.

Operation Conditions

1. Mostly applied outdoor in system of 50Hz and 60Hz

2. Max Altitude is 3500m. Because of high altitude and bad thermal discharging in plateau, please indicate in order if in this situation.

3. Ambient Temp is between -20°C~+70°C and relative humidity does not excess 95%.

4. Wind pressure does not excess 700Mpa (equivalent to 34m/s)

5. Earthquake intensity is less than 8 degree.

6. Thickness of ice coverage is less than 10mm

7. Air dusty grade is not higher than IV grade

8. No corrosive or explosive gas and conductive dust around installation site.

9. As the resistor is a heat generating component, it should be installed in place with some space left around, and be away from heat source.

2. Application

KE RUI-$a$ Dynamic Low Voltage reactive power auto compensation controller adopts the thyristor/SCR as the switch. It can improve the power factor, has good energy saving effect, can prevent the amplification of the harmonic.

3. China Fixed Type Low-Voltage Power Distribution Cabinet/Switchgear/Switchboard Dynamic Low Voltage reactive power auto compensation controller / reactive power compensation controller Advantages

Has the function of zero-cross switch, avoid the harmonic from the non-linear partsLong life span, especially in the occasion where the load and power factor change fast, the life span is much longer than compensator with contactor. Fast response within 10msNo contact switching, can be used in places with dust.No contact point switch, suitable for dusty places.With many protections, such as over voltage, over current, under voltage etc.Small maintanance workMany protections: over voltage, over current, under voltage etc.No inrush current, can be used in frequently switch occasionEquipped with reactive power compensation controller, it is automatic cycle, switch capacitor with steps, the switch time interval can be adjustable, make the reactive power consumption to be the lowest, then improve the quality of electric network, reduce the consumption of distribution system and transformerA suitable capacity can increase the power factor to more than 0.92The heat elimination slot on the bottom of the cabinet can make the device cooling immediately.The top cover of the cabinet body can be removed if necessary, it is convenient for installation and maintenance.The panel of the cabinet is spray craft, which make the product has a good touch feelProtection is IP 30, also can be changed from IP20 to IP 40

4. China KR-Fixed Type Low-Voltage Power Distribution Cabinet/Switchgear/Switchboard Dynamic Low Voltage reactive power auto compensation controller / reactive power compensation controller price working conditions

1. Indoor /outdoor using, with good ventilation2. Indoor installation, altitude is less than 1000m, no harmful gas and dust, no explosive dust3. Long time over voltage is not more than 1.1Un, long time over current is not more than1.35Un.4. Ambient temperature is less than 40 degree centigrade, when capacitor switch, the lower limit of temperature is minus 40 degree centigrade5. Humidity: less than 50% when it is 40 degree centigrade
