The circuit is composed of a two points or multiple points power supply power source, a fuse, a controllable switch, a rectification diode, a breaker, a fixed capacitor and an uninterrupted power supply line. The utility model is characterized in that the two points electricity-taking type automatic inverter for an AC line is composed of two one-way line power supply devices, and more than two multiple points one-way line power supply devices are connected in parallel, which can realize the goal of uninterrupted power supply for the line.
Description
The utility model relates to a kind of alternating current circuit two point power taking auto switching device, belongs to the power supply unit technical field.Thereby be applicable to the ac power supply line of obtaining the alternating current uninterrupted power supply from two or more power supply points, be particularly useful for wired broadcasting TV power supply unit circuit.
Before the present invention, electricity will be obtained in the alternating current circuit, can only obtain the electric energy input from a power supply supply terminals, and what take is fixedly single supply point power taking, and still, in case this power supply has a power failure, whole line facility just shuts down, and has brought difficulty and inconvenient for work and life.Fixedly single power supply circuit technology can't resolve this technical task of uninterrupted power supply.Therefore, never power cut problem be separated, backup supply line can only be set up in addition, the cost height, investment is big, the installation trouble, and can not use preferably in that real work is in service.Just currently known, have only " lightning-arrest fuse auto switching device ", the patent No.: 89207591, this design is under the situation that the single-point power supply does not stop, main fuse burns out, make relay power, impel the spare fuse line attachment and make the unimpeded a kind of lightning-arrest fuse automatic switching device of circuit, find to have with regard to technical solutions of the utility model the alternating current circuit two point power taking auto switching apparatus of same or similar part as yet both at home and abroad.
It is a kind of from two or the many places power taking, make AC energy flow to power consumption equipment, the alternating current circuit two point that guarantees running working properly or the automatic switching device of multiple spot power taking incessantly, to solve the outstanding problem that supply line has a power failure that the purpose of this utility model is to provide.
Technology implementation scheme of the present utility model is as follows: the AB end in supply line is the power supply point in two different places with A ' B ' end, and CC ', DD ' are the transmission line of alternation currents (being called for short uninterrupted power supply circuit 3,15) of uninterrupted power supply.During beginning, gate-controlled switch 2,13,4,14 is often opened, and gate-controlled switch 2,6,9,10 is normally closed.When A B end input AC electricity, circuit breaker 7 has electric current to pass through, switch 2,13 closures, simultaneously, gate-controlled switch 6 disconnects, AB end alternating current is to 3,15 power supplies of uninterrupted power supply circuit, and circuit breaker 11 is by electric current, and gate-controlled switch 10 disconnects, when at this moment if A ' B ' end power supply point has electricity to carry, because circuit breaker 12 no currents pass through, thereby gate-controlled switch 4,14 is not closed, the power supply of A ' B ' end can not be to 3,15 power supplies of uninterrupted power supply circuit.So just realized the purpose of AB end power supply point to 3, the 15 unidirectional power supplies of uninterrupted power supply circuit.
When AB end power supply point has a power failure and A ' B ' end power supply point when electricity is arranged, circuit breaker 7 dead electricity, gate-controlled switch 2,13 disconnects, gate-controlled switch 6 closures, circuit breaker 11 dead electricity, gate-controlled switch 10 closures, circuit breaker 12, gate-controlled switch 4,14 closures, gate-controlled switch 9 disconnects, and at this moment, A ' B ' end power supply point is to 3,15 power supplies of uninterrupted power supply circuit, circuit breaker 8 gets electric, and gate-controlled switch 5 disconnects.When AB end power supply point is imported as alternating current is arranged again, because gate-controlled switch 2,13 has disconnected, so AB end alternating current will not be to 3,15 power supplies of uninterrupted power supply circuit, from and realized that uninterrupted power supply circuit 3,15 can only be from the designing requirement of a supply terminals power taking.
Line work principle explanation according to above-mentioned two point power supply power supply auto switching, AB end power supply point can only be held the uninterrupted power supply line powering to CD, the CD end but can not be to the power supply of AB end, and we claim that supply line's device of being made up of the gate-controlled switch 2 of the gate-controlled switch 2,13,6 of circuit breaker 7 and control thereof and circuit breaker 8 controls is the one-way line charger.For accomplishing uninterrupted power supply, the utility model is connected two one-way line chargers, has formed alternating current circuit two point power taking auto switching device.In like manner, can take two above one-way line chargers are suitably linked to each other, carry out uninterrupted power supply.
The utility model is novel, and is reasonable in design, overcome the disadvantage that can not power continuously when having a power failure because of the power supply of fixing single-point power supply.Understand from factual survey: the probability that two or more power supply points have a power failure simultaneously almost is zero.The utility model provides the solution of present technique just at above-mentioned power supply actual conditions, and it is safe, reliable, practical and convenient, and is simple in structure, and cost is low, and the producer of general power supply unit technical field all can implement this technical scheme.
