Product Description

Product Description

 

1. Definition and use of RH-B disconnector
RH-B series disconnector is a high-voltage disconnector, mainly used for isolating power supply, switching operation and cutting off low-current circuit in power system. It is a switchgear without arc extinguishing function, suitable for high-voltage electrical places such as substations and power plants, which can ensure the safety of maintenance personnel and the normal operation of equipment.

2. Technical parameters
The main technical parameters of RH-B series disconnector are as follows (taking some models as examples):
Model Rated voltage (kV) Rated current (A) Thermal stability current (kA) Dynamic stability current (kA) Impulse withstand voltage (kV) Relative to ground/disconnector

Model Rated voltage (kV)	Rated current (A)	Thermal stability current (kA)	Dynamic stability current (kA)	Impulse withstand voltage (kV)	Phase-to-ground/disconnector
RH-B 11	11	44	12500	31500	75/95

In addition, its insulation performance is good, and the impulse withstand voltage of the disconnector and relative to ground reaches 38-80 kV respectively, which can meet the safe operation requirements of high-voltage equipment.

3. Functional features
RH-B isolating switches have the following functional features:

Isolated power supply: After opening, a reliable insulation gap is formed to isolate the maintenance equipment from the power supply to ensure the safety of personnel.
Switching operation: Switch the line according to the operation needs to adapt to different operation modes.
Carrying current: In the closed state, it can carry the normal loop current and withstand the current under abnormal conditions (such as short circuit) for a short time.
No arc extinguishing function: Since it does not have the arc extinguishing ability, it is only suitable for opening and closing operations under no-load current conditions.
4. Application scenarios
RH-B isolating switches are widely used in the following fields:
Power system: used in substations and transmission lines to isolate transformers and switchgear to ensure maintenance safety.
Industrial automation: In industrial production, it is used to isolate equipment circuits to ensure the safety of equipment maintenance.
Other fields: For example, in medical equipment, it is used to isolate circuits to protect the safety of patients and medical staff.
5. Precautions
Operational restrictions: Due to the lack of arc extinguishing function, the RH-B disconnector can only be opened and closed under no-load current conditions to avoid arcing or fire caused by improper operation.
Maintenance requirements: Regularly check the insulation performance and mechanical parts of the switch to ensure that the equipment is in good condition.
