Description
Technical field
The present invention relates to a kind of miniature circuit breaker, particularly, relate to a kind of miniature electronic formula residual current circuit breaker that is used for the experimental rig of miniature electronic formula residual current circuit breaker and has this experimental rig.
Background technology
Along with the development of electric automatization, miniature electronic formula residual current circuit breaker has become a kind of electrical equipment that is widely used in the low pressure terminal distribution system.The effect of residual current circuit breaker is that power frequency supply is carried out earth leakage protective and overload protection etc.When having people's electric shock or circuit leakage current above power failures such as settings, residual current circuit breaker can produce tripping operation etc. and protect action in the extremely short time, cut off the electricity supply automatically, guarantees personal safety, and the equipment that prevents is because of the accident that leakage current causes takes place.Residual current circuit breaker has overload and short-circuit protection function, can be used to the overload and the short circuit of protection circuit, also can be under normal circumstances as the usefulness of the not frequent transitions of circuit.
Traditional electronic type residual current circuit breaker commonly used at present, the terminals of its top are called inlet wire usually as the inlet wire of power supply, and the terminals of below are called outlet down usually as the connection of load.Usually require the wiring of the following outlet of the last inlet wire of mains side and load end can not wrong, promptly can not be connected on down outlet to power supply, and load is connected on inlet wire.In case wrong is called reversal connection line or outlet down, will make damage of product.This is because the creepage protection function of electronic type residual current circuit breaker part need be from the mains side power taking.If last inlet wire correctly is connected with power supply, then circuit breaker receives electric leakage signal and also can cut off the power supply supply of creepage protection function part when threading off; If but outlet is connected with power supply mistakenly down; even then be in off-state behind the circuit breaker tripping; the creepage protection function part also is lasting charged; and at this moment the test loop of creepage protection function part (for example is in on-state always; the testing button that the user pins residual current circuit breaker is not put); test loop can make creepage protection function part continuous firing (continue to send electric leakage signal and give circuit breaker) and cause the electronic component of creepage protection function part to burn out, thereby damages whole residual current circuit breaker.
Therefore; the damage of the residual current circuit breaker that causes in order to prevent above-mentioned wiring error from connecting; preferably make residual current circuit breaker have the function of reversal connection line; promptly; even power supply is connected on down outlet, and load is connected on inlet wire, residual current circuit breaker still can operate as normal; and circuit breaker owing to protection reason such as electric leakage or test protection former thereby thread off after when being in off-state, can not damage the creepage protection function part of residual current circuit breaker and even damage whole residual current circuit breaker.
There are some residual current circuit breaker also can use some specific structures to realize the function of above-mentioned reversal connection line in the prior art.As in Chinese patent No.03238605.2 (notification number CN 2604773Y), disclosing a kind of reversible Wiring type residual current circuit breaker; form by breaker portion and electric leakage action part; comprise pedestal; lid; fixed contact; moving contact; operating mechanism; leakage current transformer; 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 its moving contact and fixed contact closure; the electric leakage control circuit board has the power supply supply and in running order; earth leakage protective can be provided; moving contact and auxiliary contact also disconnect when moving contact and fixed contact disconnection; the electric leakage control circuit board is connected to the power line of auxiliary contact and the non-transformer supply, and the electric leakage control circuit board can not be worked.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.But the scheme of this utility model is too complicated, and cost is also high, and can't carry out the checking of life-span and reliability.
So, need a kind of can provide realize having reversal connection line function, operation miniature electronic formula residual current circuit breaker reliable, simple in structure.
