Description

Technical Field

[0001] The utility model relates to a universal circuit breaker controller dedicated to photovoltaic and wind power. Background Art

[0002] The universal circuit breaker controller for photovoltaic and wind power is a high-performance power control device specially designed for photovoltaic and wind power systems. It not only needs to have the basic functions of a conventional circuit breaker controller, but also needs to adapt to the special requirements of renewable energy power generation systems. In actual use scenarios, it is found that the internal metal parts of the universal circuit breaker controller are easily rusted and corroded due to the influence of moisture in the air during transportation and use, resulting in equipment performance degradation or failure. Even if some controllers have built-in desiccant belts, there is no prompt function, resulting in the desiccant failing to be replaced in time, which is extremely inconvenient to use.

[0018] like Figure 1-6As shown, the utility model relates to a photovoltaic and wind power dedicated universal circuit breaker controller, comprising a circuit breaker controller housing 1, a bagged desiccant 2, a humidity indicator card 3, a glass 4 and a cover plate 5. The front of the circuit breaker controller housing 1 is provided with a housing insertion cavity, and the inner wall of the housing insertion cavity is provided with a limiting partition 7. The limiting partition 7 divides the housing insertion cavity into a desiccant placement cavity 8 for placing the bagged desiccant 2, an indicator card positioning groove 9 for installing and positioning the humidity indicator card 3, and a glass positioning groove 10 for installing and positioning the glass 4. The inner wall of the desiccant placement cavity 8 is provided with a spaced arrangement of dry The desiccant flow hole 11 is provided on the side wall of the circuit breaker controller housing 1 with an observation port 12 communicating with the glass positioning groove 10. The cover plate 5 is covered on the housing insertion cavity. The humidity indicator card 3 is a conventional test piece available on the market. The bagged desiccant 2 can effectively prevent moisture and water from damaging the internal electronic components of the universal circuit breaker controller. The humidity index on the humidity indicator card 3 can be directly observed through the observation port 12. When the humidity index exceeds the expected value, it indicates that the internal bagged desiccant 2 needs to be replaced. It can be quickly replaced by opening the cover plate 5. The operation is simple and the indication is clear. It is convenient and quick to use and the overall cost is low.

[0019] The cover plate 5 includes a cover plate cover body 13, one end of the cover plate cover body 13 is provided with a cover plate limiting protrusion 14, the other end of the cover plate cover body 13 is provided with a cover plate clamp 15, the front of the circuit breaker controller housing 1 is provided with a housing positioning groove 17 for positioning the cover plate cover body 13 at the periphery of the housing insertion cavity, the housing positioning groove 17 is provided with a housing socket 18 for inserting the cover plate limiting protrusion 14 at one end close to the observation port 12, and the other end is provided with a bayonet docking groove 19 docking with the cover plate clamp 15. The cover plate has a compact structure, is firmly and reliably installed, and is not easy to fall off.

[0020] The cover plate clamp head 15 includes a bayonet arc transition portion 21 and a cover plate hand-operated portion 22 which is on the same horizontal plane as the cover plate cover body 13. The bayonet arc transition portion 21 is provided with a cover plate clamping block 24 on the front and rear sides of the cover plate hand-operated portion 22.
