Description: Neutral grounding resistor cabinet, is in the neutral and ground grid connected in series between a resistor. Select the appropriate value of the resistor connected not only single-phase electric arc discharge half wave energy, thereby reducing the possib

WF-B series of neutral grounding resistor components using resistance special, special formula stainless steel alloy, the main characteristics are:

.Withstand high temperatures: melting point (1375-1500 ), the maximum temperature 1000 ;

.High tensile strength: tensile strength 700MPa, at 900-1000 high temperature, mechanical strength remained unchanged;

.High resistance: Resistance was 1.25μΩ.m, helps to reduce the size of the resistive element;

.weighed resistance: resistance temperature coefficient of 1.05 × 10-4 / , when 350 high temperature, the resistance increased only 4% (iron resistive element resistance increased by 24%), helping to ensure the protection of sensitivity;

. Strong antioxidant capacity: at a high temperature of about 1000 still maintain good oxidation resistance. Suitable for polluting the environment;

.High toughness: the dramatic changes in temperature operating conditions remain good toughness, not easy to break;

.Type complete: In accordance with the size of the flow capacity with ribbon, grid, spiral wound type, rib-wound type. Wound smooth results and other types of resistive element.

Check the test: when reliable equipment on, open the front panel with nameplate for, check the wiring inside the device, and note the following:

. Charged money for all packaging materials must be removed from the box, in order to avoid the occurrence of a fire;

. Carefully check whether the insulators, bushings, etc. are damaged, if found damaged parts, hard immediately contact haulers;

. Check the tightening of the screw is indeed removed;

. Check all electrical connections, make sure connections are secure and reliable;

. All the fixing bolts are tightened;

. Put into operation before the test, measuring the resistance of the resistive element, measure the insulation resistance, according to the standard frequency voltage withstand test. The test voltage is not more than 85% of the factory test voltage value;

. Also good original cabinet front panel, ready to put into operation.
