Six characteristics of low voltage isolation switch, third and its important
Six characteristics of low voltage isolation switch
Low voltage isolation switch as a safety switch, is widely used in power distribution system, but there are
many enterprises do not understand because its performance characteristics, and at the time of purchase
misunderstanding, following small to count, about six errors common isolation switch.
1 isolation switch and knife switch is a kind of product?
Explanation: refers to the isolation switch in the open position, can satisfy a switch provided for isolator
requirements, is one of the switch, which is to say, including knife switch, isolating switch.
2 isolation switch does not have any effect?
Interpretation: This is not the correct concept, the isolation switch is a sign of a clear short circuit in
the electrical workers, maintenance, you can remind and protect the personal safety of maintenance
personnel, an indispensable.
3 isolation switches can call the master switch?
Explanation: the isolation switch is in the maintenance of the circuit to ensure the disconnection of the
switch, it does not destroy the arc device, it is generally used to cooperate with the main switch, but
not directly when the master switch.
4 low voltage electrical switches can also be used for high pressure?
Explanation: low voltage electrical is the electrical equipment that works at DC1500V, AC1000V.
When the voltage is higher than this value, it is easy to produce the arc isolating switch bare copper
bar and no arc device characteristics are likely to endanger the operation of people's life, so the low
voltage isolation switch is absolutely not for high pressure.
5 isolation switches must be used with the circuit breaker.
The isolation switch can replace the isolating knife and the fuse, and the arc extinguishing device is added,
and the fuse type isolating switch uses the fuse to replace the circuit breaker.
6 isolation switches must choose "foreign brands"?
The main factors that determine the quality of the isolation switch are: material and die. This makes some
domestic brands (such as jinlaile electric) product quality is not inferior to the international brand, can be
assured to buy.
