Abstract
The utility model discloses a collection flow box with overload protection, its inner member include fuse, detection module, busbar, direct current lightning protection device and direct current breaker, its characterized in that: the last switch quantity output that is equipped with of detection module, the last parallelly connected shunt release that has of direct current breaker. Wherein, the last still parallelly connected auxiliary contact that is equipped with of direct current breaker. The utility model discloses beneficial effect is: direct current collection flow box the overload appears and divides disconnected function occasionally automatically, can the effectual trouble that prevents further enlarge.
Description
Technical field
This utility model relates to photovoltaic intelligent electrical network field, particularly relates to a kind of header box with overload protection.
Background technology
In recent years, photovoltaic products achieves quickly development, the photovoltaic combiner box product supporting with it is used the most in a large number, during using, the operation maintenance in later stage seems and becomes more and more important, owing to although traditional direct current conflux case is configured with watch-dog, but a simply monitoring module, it is only able to detect the electric current on every road, voltage, then Central Control Room is uploaded to by RS485 communication, when collecting stream, alarm signal can only be sent during the fault-signals such as overload, owing to photovoltaic scene area is big, scope is wide, Deng attendant be on the scene handling failure time possible range expanded a lot, thus cause immeasurable loss.Therefore, when solving direct current conflux case security of system and remote disjunction in Photovoltaic new energy system not in time, it has also become problem to be solved.
Utility model content
The purpose of this utility model is to overcome problem above, is to be achieved through the following technical solutions:
A kind of header box with overload protection; its inner member includes fuse, detection module, bus-bar, DC lightning prevention device and dc circuit breaker; it is characterized in that: equipped with output switch parameter on described detection module, described dc circuit breaker is parallel with shunt release.
Further, the most in parallel equipped with auxiliary contact on described dc circuit breaker.
This utility model provides the benefit that:
There is the function having automatic disjunction during overload in direct current conflux case, can effectively prevent fault from expanding further.
Accompanying drawing explanation
Fig. 1 is the enlarged drawing of this utility model bus-bar.
Detailed description of the invention
Below in conjunction with embodiment, describe this utility model in detail.
A kind of header box with overload protection; its inner member includes fuse, detection module, bus-bar, DC lightning prevention device and dc circuit breaker; it is characterized in that: equipped with output switch parameter on described detection module, described dc circuit breaker is parallel with shunt release；Wherein, the most in parallel equipped with auxiliary contact on dc circuit breaker.
When breaking down, monitoring module sends power-off signal at once, dc circuit breaker is disconnected, simultaneously auxiliary contact by the feedback of status of chopper to Central Control Room, so can in time trouble point be broken from whole photovoltaic system, prevent fault from expanding further, leave the time of abundance to in-situ processing fault to in-situ processing fault can to again attendant.
The foregoing describe citing of the present utility model, illustrate principal character and advantage of the present utility model.It should be appreciated that this utility model is not restricted to the described embodiments, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.
Claims (2)
