FG-ZRB type composite resistive capacitive absorber

Product Introduction

FG-ZRBType CompositeResistance capacitance absorptionThe device is a specialized equipment that effectively protects against operating overvoltage and atmospheric overvoltage. It has the dual functions of a resistance capacitance absorber and a lightning arrester, and can be widely used in vacuum circuit breakersOperation of vacuum contactors, etcGeneratorIn electric motors, transformers, reactors, and distribution lines.

Technical Parameter

FG-ZRBType CompositeResistance capacitance absorptionThe technical data of the device is shown in the following table:

pour：

1. (F) is an optional item with an action counter;

2. be directed against35kVWeak insulation equipment in the system, such as electric furnace transformers, can be specially designed with a capacity of0.2µFProducts to enhance protection;

3. Various non-standard models can be customized with parameters according to specific customer requirements;

During the capacitor acceptance test, the DC withstand voltage value of the capacitor is taken as 0.75 times the withstand voltage in the technical data sheet, and the time is 10 seconds.

3. Altitude not exceeding3000m，exceed3000mIt can be customized according to the actual situation.

4. earthquake intensity7Areas of degree and below; Maximum wind speed not exceeding35m/S.

5. Grid frequency:58～62Hz（60HzSystem),48～52Hz（50HzSystem).

6. The air in the installation site should not contain chemical corrosive gases and vapors, and there should be no explosive dust.

7. The minimum nominal creepage distance of the jacket shall not be less than20mm/kVSuitable for use in moderately polluted areas.

Instructions for use

1. FG-ZRBThe composite resistance capacitance absorber should be connected to the outlet current of the vacuum circuit breaker (vacuum contactor)mutual inductanceimplementBetween the lower side and the protected equipment (such as electric motors or transformers), as shown in the figure1As shown.

2. FG-ZRBType CompositeRX-ZRBDivided intoZType (suitable for protecting generators and motors) andPType（Suitable for protecting distribution transformers, reactors, and lines, appropriate products should be selected for ordering and installation according to the protected objects.3. FG-ZRBWhen the type of composite resistance capacitance absorber is taken out of operation and checked, it should beO-NDischarge the resistance capacitance circuit between them.

Transportation and Storage

1. FG-ZRBThe composite resistance capacitance absorber should be packed and transported in a rainproof, light, upright, and anti-collision manner during transportation.

2. When stored, it should be kept in an upright position, and the storage location should have an ambient temperature of -40℃～＋40Flammable and explosive gases and chemicals are not allowed within the temperature range of ℃.
