The circuit breaker is called the high-voltage switch, it is one of the most important equipment in transformer substation, it not only may shut off and closed high electric circuit's zero-load current and the load current, moreover works. And when phylogeny breakdown, the circuit breaker and the protective device and the automatic device coordinates get together, excises the fault current rapidly, reduces the power cut scope, the forestall trouble expands, guarantee system safe operation.

According to the arc-control device, the arc-extinguishing medium may divide into:

1. oil circuit breaker (few oil circuit breakers and multi-oil circuit breakers);
2. air circuit breaker; the
3. magnetism blows the circuit breaker;
4. vacuum circuit-breaker;
5. sulfur hexafluoride circuit breaker.

May divide into according to the operating mechanism nature:

1. holds electrically operated moves the structure circuit breaker;
2. hydraulic pressure holds moves the structure circuit breaker;
3. air operated holds moves the structure circuit breaker; 
4. spring stored energy holds moves the structure circuit breaker;
5. manual holds moves the structure circuit breaker.

May divide into according to the installation site:

1. indoors type circuit breaker;
2. outdoors type circuit breaker;
3. explosion-proof type circuit breaker,
