KMG-01 Outdoor Household Circuit Breaker

After switching from overhead lines to insulated lines, line faults have been greatly reduced. In order to simplify relay protection, the center point of the transformer is grounded through a small resistor. In this case, when the single-phase grounding current reaches a certain value, the feeder circuit breaker of the substation will trip, causing a power outage of the entire line. In order to prevent user faults from being reflected in the substation (or higher-level circuit breaker), a household circuit breaker (referred to as a watchdog) is installed at the user entrance. When there is a fault in the user's internal circuit, the household circuit breaker trips, isolating the user's internal fault from the main circuit. The controller determines the user's working status based on the current parameters emitted by the circuit breaker. When the current exceeds the rated set value, it issues a trip command to trip the circuit breaker. In this way, the fault point can be located in the fault section. That is to say, internal faults within the user will not affect the entire line.

Product features of KMG-01 outdoor household circuit breaker:

1. Adopt air silicone rubber and engineering plastic composite insulation.
2. Voltage transformers can be installed inside the switch to provide operational power and voltage sampling.
3. The plan is flexible and can reserve interfaces for automatic distribution, facilitating the development of distribution automation.
4. The incoming and outgoing lines are arranged in an "L" shape.
5. Combined with the controller, it can be used as an automatic recloser or automatic segmenter.
6. After the voltage transformer loses voltage, at least one opening operation shall be performed by the built-in capacitor
