Abstract
The utility model relates to a kind of emergency generator overload protection arrangement, belongs to generator car control device technical field.Technical scheme is: after current relay (3), the time relay (4) connect successively, two ends are connected to each other formation trip control unit with the two ends of breaking coil (5), device relay (6) respectively, fuse (7) has two, be separately positioned on the two ends of trip control unit, circuit breaker (1), current transformer (2) connect successively, are connected to each other by current relay (3) and trip control unit.The beneficial effects of the utility model are: by utilizing Principles of Relay Protection; breaking coil can give the actuating of relay Signal transmissions rapidly in the case of an overload, deenergization, effectively ensures the safety of generating equipment; after lightening the burden, can emergency service be dropped at once, ensure power supply continuity.
Description
Technical field
The utility model relates to a kind of emergency generator overload protection arrangement, belongs to generator car control device technical field.
Background technology
Current emergency generator has only installed low-voltage circuit breaker usually as current protection, and low-voltage circuit breaker only just can instantaneous operation when reaching about 10 times rated current, or need in the case of an overload for a long time could action.When load current do not reach instantaneous operation value but reached the overload current that generator can not bear time, will cause burning of generator coil, this not only causes very large economic loss to us, also creates very bad social influence simultaneously.
Utility model content
The utility model object is to provide a kind of emergency generator overload protection arrangement; make use of Principles of Relay Protection; breaking coil can give the actuating of relay Signal transmissions rapidly in the case of an overload; deenergization; the safety of effective guarantee generating equipment; after lightening the burden, can emergency service be dropped at once, efficiently solve the problems referred to above existed in background technology.
The technical solution of the utility model is: a kind of emergency generator overload protection arrangement, comprise circuit breaker, current transformer, current relay, the time relay, breaking coil, device relay, fuse and line terminals row, described current relay, after the time relay connects successively, two ends respectively with breaking coil, the two ends of device relay are connected to each other formation trip control unit, fuse has two, be separately positioned on the two ends of trip control unit, circuit breaker, current transformer connects successively, be connected to each other by current relay and trip control unit.
Described device relay is static relay.
The beneficial effects of the utility model are: by utilizing Principles of Relay Protection; breaking coil can give the actuating of relay Signal transmissions rapidly in the case of an overload, deenergization, effectively ensures the safety of generating equipment; after lightening the burden, can emergency service be dropped at once, ensure power supply continuity.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
In figure: circuit breaker 1, current transformer 2, current relay 3, the time relay 4, breaking coil 5, device relay 6, fuse 7, line terminals row 8.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of emergency generator overload protection arrangement; comprise circuit breaker 1, current transformer 2, current relay 3, the time relay 4, breaking coil 5, device relay 6, fuse 7 and line terminals row 8; after described current relay 3, the time relay 4 connect successively; two ends are connected to each other formation trip control unit with the two ends of breaking coil 5, device relay 6 respectively; fuse 7 has two; be separately positioned on the two ends of trip control unit; circuit breaker 1, current transformer 2 connect successively, are connected to each other by current relay 3 and trip control unit.
Described device relay 6 is static relay.
Static relay selected by device relay, prevents the vibrations due to generator to cause the misoperation of relay contact.
Claims (2)
1. an emergency generator overload protection arrangement, it is characterized in that: comprise circuit breaker (1), current transformer (2), current relay (3), the time relay (4), breaking coil (5), device relay (6), fuse (7) and line terminals row (8), described current relay (3), after the time relay (4) connects successively, two ends respectively with breaking coil (5), the two ends of device relay (6) are connected to each other formation trip control unit, fuse (7) has two, be separately positioned on the two ends of trip control unit, circuit breaker (1), current transformer (2) connects successively, be connected to each other by current relay (3) and trip control unit.
2. according to a kind of emergency generator overload protection arrangement described in claim 1, it is characterized in that: described device relay (6) is static relay.
