The main effect of isolating switch:
1, points after the brake, to establish a reliable insulation clearance, will need to repair the equipment or with an obvious disconnect point for all power lines and separated.
2, according to the operation in line."
3, can be used to points, small current in a circuit, such as casing, busbar cables, connectors, short charging current, pressure switch capacitance of capacitive current.
4, can be used to divide, close a certain capacity of transformer no-load excitation current.
5, isolated power supply, high pressure maintenance equipment and electric equipment disconnected, clearly visible breaking point.
1, the circuit breaker shall be configured on both sides of the isolating switch, so that when the circuit breaker maintenance form obvious fracture from the power supply.
2, ordinary transformer neutral point grounding directly, all should be grounded by isolating switch.
3, on the bus the lightning arrester and voltage transformer, appropriate share a set of isolating switch, to ensure the safety of electric equipment and bus maintenance, each bus bar should be installed on 1 or 2 set breaker.
4, lead wire in transformer or neutral arrester don't furnish isolating switch.
5, when the user side of the feeder circuit without power supply, circuit breaker to the user's side can not furnish isolating switch. But in order to prevent lightning overvoltage, can also be installed.
We can provide isolation switch and switch internal accessories, independent production
