Description
Technical field
The utility model belongs to breaker technical field, is specifically related to a kind of on-load switch and Combined switch of circuit breaker.
Background technology
On-load switch is according to using voltage can be divided into high voltage load switch and low voltage switch. The operation principle of high voltage load switch is similar to breaker. Simple vacuum interrupter is generally housed, but it is relatively simple for structure. Low voltage switch claims again switch fuse group. Be suitable in AC power frequency circuit, with manually not continually break-make have live road; Also can be used for overload and the short-circuit protection of circuit. On-load switch is mainly used in cut-offfing and closing load current, also on-load switch and high-tension fuse can be used in conjunction with, and replaces breaker. On-load switch is a kind of device for switching between breaker and isolating switch, has simple vacuum interrupter, can cut off rated load electric current and certain overload current, but can not cutting-off of short-circuit electric current. But existing on-load switch function singleness can not meet on power circuit and use, therefore, need to be improved, therefore, in the urgent need to improving, provide a kind of new on-load switch.
