Description
Technical field
The present invention relates to a kind of Minitype electrical leakage breakers and intelligence to take control switch（Autoreclose breaker）.
Background technology
Minitype electrical leakage breaker includes mainly electric leakage module and breaker module, and electric leakage module is also known as " N electrode systems ",
Therefore, Minitype electrical leakage breaker is properly termed as " 1P+N ", " 3P+N " again according to the different of breaker module quantity.Small-sized electric leakage
The operation principle of breaker is when leaking electricity in circuit or electrical equipment, and zero sequence transformer can send a signal to wiring board,
Wiring board controls buckle releaser work, makes circuit breaker tripping to cut off circuit, protects electric appliance in circuit.Existing small-sized electric leakage is disconnected
Road device is broadly divided into zero sequence transformer internally-arranged type and zero sequence transformer externally positioned type according to the installation position of zero sequence transformer, wherein
Zero sequence transformer internally-arranged type can be found in following several documents.
If China Patent Publication No. is 204857640, it discloses a kind of energy-saving leakage protection modules, by its attached drawing 2
In it can be seen that zero sequence transformer be arranged in the shell of electric leakage module.
If China Patent Publication No. is 205810713, it discloses a kind of leakage circuit breakers N electrode systems comprising shell,
Wiring board is equipped with below enclosure interior, the wiring board side is equipped with the axis zero-sequence mutual inductance parallel with the shell length direction
Device is additionally provided with tripping mechanism in the shell, and the tripping mechanism includes that contact is supported, the contact is supported to be equipped with dynamic touch
Head, the inner walls are equipped with arc-chutes corresponding with the moving contact.
Since zero sequence transformer is set up directly in electric leakage module in above structure, by taking " 1P+N " as an example, breaker module
The poles L terminals need by conducting wire pass through zero sequence transformer after return in breaker module；Therefore, it is necessary to conducting wire it is longer,
The conducting wire for meeting L simultaneously needs to penetrate into electric leakage module, reduces the remaining space in electric leakage module, therefore there is temperature and increase, lead
The problems such as wiring caused by line is long is inconvenient, conducting wire junction is easy to cut-off, and breaker is difficult to assemble.Such problem, in 3P+
The case where occurring in the leakage circuit breakers of N is even more serious, because the poles the L terminals of each breaker module are required for passing through conducting wire
It is revert to after zero sequence transformer in corresponding breaker module, therefore, the conducting wire in electric leakage module can be made on the high side, caused
Remaining space in electric leakage module becomes smaller, and the quantity of conducting wire is more and the problem of temperature rise of longer initiation, wiring is unstable, is difficult to assemble
The problems such as it is extremely serious.
Invention content
It is an object of the invention to overcome the deficiencies of existing technologies, a kind of Wen Sheng little, the small-sized electric leakage that wiring is stablized are provided
Breaker.
To achieve the above object, the present invention uses a kind of Minitype electrical leakage breaker comprising electric leakage module and breaker
