Technical field
The invention belongs to switching technique field, and in particular to a kind of load stacked switch.
Background technology
On-load switch (Load switch) can be divided into high voltage load switch and low according to using voltage
Pressure on-load switch.The operation principle of high voltage load switch is similar to breaker.It is generally equipped with simple
Vacuum interrupter, but its is relatively simple for structure.Low voltage switch is also known as switch fuse group.It is suitable
In AC power frequency circuit, so that infrequently break-make has load circuit manually；Can also be used for the mistake of circuit
Carry and short-circuit protection.On-load switch is mainly used in cut-offfing and closing load current, it is also possible to by load
Switch is used cooperatively with high-tension fuse, instead of breaker.On-load switch be between breaker and every
A kind of device for switching between closing is left, with simple vacuum interrupter, rated load can be cut off
Electric current and certain overload current, but short circuit current can not be cut off.But existing on-load switch function
It is single, it is impossible to meet and used on power circuit, accordingly, it would be desirable to improved, therefore, compel to be essential
Improve, there is provided a kind of new on-load switch.
