Embodiment
Below in conjunction with accompanying drawing, the utility model scheme is elaborated.
As Fig. 1, the case that the present embodiment provides becomes the automatic power transmission device of adjustable delay, is mainly made up of circuit breaker deciliter control loop and time delay automatic closing control loop.The change over switch communication connection of time delay automatic closing control loop and circuit breaker deciliter control loop.
Wherein, a circuit breaker deciliter control loop comprises closing circuit.Closing circuit comprises that change over switch and case become incoming line cabinet circuit breaker.Change over switch is by the first time-delay relay and switch knob and the communication connection of case change incoming line cabinet circuit breaker.In the present embodiment, change over switch adopts HZ5B-10Z/2 specification.
Automatic closing control loop mainly, by manual branch road and automatic branch road, manually props up route auxiliary contact, the second time-delay relay and the 3rd time-delay relay and composes in series successively.Automatic support route the first auxiliary relay and the second auxiliary relay compose in series.Wherein, the second time-delay relay adopts (JS14P-27, AC220V, 10-9990S) specification, and the 3rd time-delay relay adopts (JS14P-21, AC220V, 0.1S-9.9S) specification.In the present embodiment, change over switch is respectively equipped with hand switch shelves and automatic switch shelves.Manually branch road and hand switch communication connection; Automatically branch road and automatic switch communication connection.
Case becomes incoming line cabinet circuit breaker and also comprises under-voltage loop, divide-shut brake loop, separating brake instruction loop and the instruction loop of closing a floodgate.Case becomes incoming line cabinet circuit breaker and is respectively equipped with input port and output port corresponding to under-voltage loop, divide-shut brake loop.Case becomes incoming line cabinet circuit breaker and indicates loop, closes a floodgate and indicate loop to be respectively equipped with input port and to be provided with same output port corresponding to separating brake.
Separating brake instruction loop corresponding to the case input port that becomes incoming line cabinet circuit breaker be connected with opening button DA.
Separating brake instruction loop, the instruction loop of closing a floodgate become corresponding to case incoming line cabinet circuit breaker input port be respectively equipped with separating brake indicator light and combined floodgate indicator light.
The two ends of under-voltage loop, manual branch road, automatic branch road and automatic closing instruction branch road connect control power supplys by four fuses respectively.Referring to Fig. 1, fuse is respectively FU1, FU2, FU3, FU4.
The first time-delay relay, the second time-delay relay and auxiliary relay composition delay circuit.In the present embodiment, the first time-delay relay adopts (JS14P-27, AC220V, 10-9990S) specification, and the second time-delay relay adopts (JS14P-21, AC220V, 0.1S-9.9S).
