The following describes concrete device:
Breaker of plastic casing 2, also automatic load switch is claimed, the general 800V of nominal insulation voltage, be applicable to exchange 50Hz and 60Hz, rated operational voltage is to 690V and following low voltage power distribution network, mould shell and refer to the shell being used as device with plastic insulation, be used between insulated conductor and ground metal portion.It can be used to connect and disjunction load circuit; loaded current value arrives hundreds of ampere tens; protection circuit and power-supply device are from the damage of the faults such as overload, short circuit, under voltage; simultaneously also can as the infrequently starting of motor and overload short circuit under voltage protection; can protection circuit and power-supply device not be damaged; this circuit breaker 2 has the features such as volume is little, point broken height, arcing are short, anti-vibration, is thus widely used in markets such as building, electric power, telecommunications.
Shunt release 3 is exactly that a switching winding adds release in essence.Heat is threaded off and electromagnetic trip also uses this release.Add the voltage of regulation to shunt opening trip coil, circuit breaker 2 is just threaded off and separating brake, and shunt release 3 is commonly used in the control of far distance automatic power-off.Far can not control combined floodgate at once after circuit breaker 2 shunted exciter tripping, can not direct closing by hand, can close a floodgate after circuit breaker 2 must being detained again, this and overload wait thread off trip after to detain again the same.The difference of Here it is shunted exciter tripping and electric operating separating brake.Circuit breaker 2 operating handle has three positions, and except upper point lower conjunction two positions, after threading off, handle will rest on centre position.So-called button is again exactly that the position of to be pulled from centre position by handle point makes release again hook, and then could close a floodgate.Shunt opening trip coil voltage kind has AC and DC, and voltage swing has various electric pressure.Shunt opening trip coil can only be energized the short time, and the time burns out once long; So the auxiliary normally open contact 5 of a circuit breaker 2 will be connected in series in control loop, when circuit breaker 2 is at closing position, this contact closure, circuit breaker 2 is when separating brake or trip positions, this contact is opened, and automatically can cut off the electric current of shunt opening trip coil after circuit breaker 2 is threaded off.

The operation principle with the circuit breaker of the function that prevents from privately sending a telegram in reply is as follows:
When electric company because of arrearage or other reasons for implementing certain client to have a power failure time, the circular shaped motion window of three-phase electricity meter box side can be opened, with supporting private key, key switch 8 is rotated to the position of conjunction, key is pulled up simultaneously, key switch normal opened contact 4 will by assigning to conjunction, shunt opening coil 6 obtains alternating current 220V and controls power supply, breaker of plastic casing 2 instantaneous operation is made to thread off, even if the position that after threading off, handle is pulled point by client from centre position makes release again hook, again close a floodgate again and can not close, because the key switch normal opened contact 4 in key switch 8 closes all the time, as long as client attempts breaker of plastic casing 2 to be pulled the position of closing, then auxiliary normally open contact 5 just will close, shunt opening coil 6 again obtains alternating current 220V and controls power supply, breaker of plastic casing 2 instantaneous operation is made again to thread off, thus make breaker of plastic casing 2 all the time can not on normal occlusion.Reach once implement power failure behavior, the object that client just can not send a telegram in reply privately.
After enforcement arrearage has a power failure, breaker of plastic casing 2 is in trip positions, and breaker of plastic casing 2 is also in this centre position when breaker of plastic casing 2 persistent overcurrent or short circuit tripping operation, this causes an illusion with regard to easy to client, be hard to tell is that the arrearage that power supply enterprise implements has a power failure or its inner overload on earth, short circuit causes breaker of plastic casing 2 to thread off, so connect an arrearage power failure indicator 7 after the key switch normal opened contact 4, this lamp is arranged near low pressure ammeter box breaker of plastic casing 2 operating handle, and indicate " arrearage power failure " printed words, urge expense librarian use private key to be had a power failure by breaker of plastic casing 2 after separating brake like this when checking meter, , along with key switch normal opened contact 4 closes, namely this lamp is synchronously lighted, client's nature after sensation has a power failure can arrive ammeter box and check breaker of plastic casing 2 state, understand it is the power failure that arrearage causes at a glance.
After client pays up arrearage or meets power transmission condition, power supply is checked meter and is urged expense personnel can again open circular shaped motion window, utilize the position that key switch 8 is screwed into point by private key, key is pulled up simultaneously, then key switch normal opened contact 4 is instantaneous will by be incorporated into point, arrearage power failure indicator 7 dead electricity will by bright to going out, shunt release 3 controls power cut-off simultaneously, namely shunt release 3 is no longer implemented to control to breaker of plastic casing 2, after the position of now to be pulled from middle trip positions by breaker of plastic casing 2 handle point makes release again hook, just can again close a floodgate.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.
