Abstract
The utility model discloses a reversible wiring leakage breaker consisting of a breaker part and a leakage action part, which includes a base, a cover, a static contactor, a dynamic contactor, an operating unit, a zero sequence current transformer, a leakage control circuit board and a release. The utility is characterized in that provided nearby the static contactor is an auxiliary contactor to which the power cord of the leakage control circuit board is connected. When the dynamic contactor closes the contact with the static contactor, the dynamic contactor also closes the contact with the auxiliary contactor, the leakage control circuit board still has power on, which can provide leakage protection; when the dynamic contactor disconnects with the static contactor, the dynamic contactor also disconnects with the auxiliary contactor. No power is provided to the power cord of the leakage control circuit board, which is connected to the auxiliary contactor, thereby the leakage control circuit board can not work. Therefore, when the power cord is reversely connected, the leakage breaker can still implement the protection without damage to the breaker line or the release.
Description
Affiliated technical field
The utility model belongs to the low-voltage electrical apparatus field, refers in particular to the residual current circuit breaker of a kind of family expenses and similar applications.
Background technology
Residual current circuit breaker is made up of breaker portion and electric leakage action part, comprise pedestal, lid, fixed contact, dynamic static joint, operating mechanism, zero sequence current mutual inductor, electric leakage control circuit board, release, its operation principle is: when residual current circuit breaker during in normal operation, pass each phase current balance at the turnover two ends of zero sequence current mutual inductor, vector and be zero, zero sequence current mutual inductor secondary side no-output; When electric leakage or person electric shock occurring, the zero sequence current mutual inductor secondary coil induces residual current, the electronic circuit of residual current on the electric leakage control circuit board amplifies, release is subjected to this current excitation, make circuit breaker tripping and open circuit, promptly when residual current equaled specified residual current acting value (I Δ n), release will move, and makes breaker open operation.At present, the residual current circuit breaker of selling on the market, existing power supply and load end wiring can not mistake, will make the defective of damage of product in case make a mistake, and therefore indicates " power supply " and " load " at the Wiring port of pedestal.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of reversible Wiring type residual current circuit breaker is provided, and it has the function of reversible wiring.
For achieving the above object, the solution that the utility model is taked is: a kind of reversible Wiring type residual current circuit breaker, form by breaker portion and electric leakage action part, comprise pedestal, lid, fixed contact, dynamic static joint, operating mechanism, zero sequence current mutual inductor, the electric leakage control circuit board, release, it is characterized in that near fixed contact, also being provided with auxiliary contact, the power line of electric leakage control circuit board is connected to auxiliary contact, moving contact and auxiliary contact are also closed when moving contact and fixed contact closure, and moving contact and auxiliary contact also disconnect when moving contact and fixed contact disconnection.
Because the utility model also is provided with auxiliary contact near fixed contact, when main contact (moving contact and fixed contact) when being in open position, auxiliary contact also is in open position, and the electric leakage control circuit board is connected to the power line non-transformer of auxiliary contact, and the electric leakage control circuit board can not be worked.When main contact was in the close position, auxiliary contact also was in the close position, and the electric leakage control circuit board has power supply in running order, and earth leakage protective can be provided.So after power line connect instead, residual current circuit breaker also can shield, and the residual current circuit breaker circuit was burnt out or the release damage.
Description of drawings
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is that the master of present embodiment looks the part cutaway view.
Among the figure: 1, lid, 2, moving contact, 3, fixed contact, 4, auxiliary contact, 5, pedestal.
Embodiment
Referring to Fig. 1, a kind of reversible Wiring type residual current circuit breaker, form by breaker portion and electric leakage action part, comprise pedestal 5, lid 1, fixed contact 3, dynamic static joint 2, operating mechanism, zero sequence current mutual inductor, electric leakage control circuit board, release, it is characterized in that near fixed contact 3, also being provided with auxiliary contact 4, the power line of electric leakage control circuit board is connected to auxiliary contact 4, moving contact 2 is also closed with auxiliary contact 4 when moving contact 2 and fixed contact 3 closures, and moving contact 2 and auxiliary contact 4 also disconnect when moving contact 2 and fixed contact 3 disconnections.
