Description

A kind of photovoltaic combiner box
Technical field
The utility model is related to header box, more particularly to photovoltaic generation header box.
Background technology
For large-sized photovoltaic grid-connected system, in solar photovoltaic generation system, in order to reduce solar photovoltaic Line between pond array and inverter uses header box.User can be by certain amount, specification identical photovoltaic cell string Connection gets up, and constitutes photovoltaic tandem one by one, then again by several photovoltaic tandems parallel connection access photovoltaic conflux lightning protection box, in photovoltaic After confluxing in lightning-proof header box, by controller, DC power distribution cabinet, photovoltaic DC-to-AC converter, AC power distribution cabinet/AC distribution panel is supported the use so as to structure Into complete photovoltaic generating system, realize grid-connected with civil power.
At present, confluxed circuit using monitoring unit and breaker protection more than the header box of in the market, so need prison in real time The traffic condition in header box is controlled, artificial solution is needed when encountering problems, if the minor issue for not influenceing electric current to transport, also has Header box may be caused to be stopped, the efficiency that will so influence electric current to transport.
Utility model content
The utility model aims to provide a kind of photovoltaic combiner box so that header box can transport circuit with cascade protection, no longer Artificial monitoring is needed, in the case where not influenceing electric current to transport, the minor accident of generation automatic inside header box can be solved, Both space in the case of header box had been saved, the volume of header box has been reduced, cost of labor is reduced again.
To solve the above problems, a kind of photovoltaic combiner box that the utility model is provided employs following technical scheme:
A kind of photovoltaic combiner box, including casing and transport assembly;Described transport assembly is located in described casing, with institute The casing stated is fixedly connected.Described transport assembly includes AC small breaker, breaker of plastic casing, fuse, communication lightning-protection Device and ground are arranged;Described AC small breaker is located at described header box high order end, is fixedly connected with described casing;It is described Breaker of plastic casing be located at described AC small breaker right, be fixedly connected with described casing;Described fuse position In described breaker of plastic casing right, it is fixedly connected with described casing;Described communication lightning-protection device is located at described fuse Lower section, is fixedly connected with described casing;Described ground is ranked below described communication lightning-protection device, is fixed with described casing Connection.
Further, described bottom half is provided with input port, and described input port is located on the left of described bottom half, Bottom half described in insertion.
Further, described input port quantity is no less than one.
Further, described bottom half is provided with delivery outlet, and described delivery outlet is located on the right side of described bottom half, Bottom half described in insertion.
Further, described output port number is no less than one.
Further, the quantity of described input port is more than the quantity of described delivery outlet.
The beneficial effects of the utility model are:A kind of photovoltaic remittance electronic box that the utility model is provided uses multiple protective, Using multiple breaker, cascade protection transport circuit does not influence overall power transmission in the case of no extreme danger, eliminates prison The setting of unit is controlled, power distribution cabinet installing space had both been saved, and had improved equipment safety, is safeguarded while facilitate to install again.
Brief description of the drawings
Accompanying drawing 1 is the front view of the casing of the utility model preferred embodiment.
Accompanying drawing 2 is the front view of the transport assembly of the utility model preferred embodiment.
Wherein:1. casing, 2. AC small breakers, 3. breaker of plastic casing, 4. fuses, 5. communication lightning-protection devices, 6. ground Row, 7. input ports, 8. delivery outlets.
Embodiment
In order to be better understood upon the technical scheme of the utility model offer, below in conjunction with the accompanying drawings with specific embodiment pair The utility model is described further.
As shown in drawings, a kind of photovoltaic combiner box provided for the utility model, including casing 1 and transport assembly;It is described Transport assembly be located at described casing 1 in, be fixedly connected with described casing 1.
Described transport assembly includes AC small breaker 2, breaker of plastic casing 3, fuse 4, communication lightning-protection device 5 and ground Row 6;Described AC small breaker 2 is located at described header box high order end, is fixedly connected with described casing 1, for even The input cable of photovoltaic group string is connect, is that each input cable is protected;Described breaker of plastic casing 3 is located at described exchange The right of miniature circuit breaker 2, is fixedly connected with described casing 1, connects the cable after confluxing, the whole described transport group of protection Part;Described fuse 4 is located at the described right of breaker of plastic casing 3, is fixedly connected with described casing 1, for connecting output Circuit, protects the cable after collecting;Described communication lightning-protection device 5 is located at the described lower section of fuse 4, solid with described casing 1 Fixed connection, for protecting, described header box can be used normally in thunderstorm weather;Described ground row 6 is located at described exchange The lower section of lightning protection device 5, is fixedly connected with described casing 1, for cable grounding.
Because each photovoltaic group string Current Voltage is smaller, it is therefore desirable to which described AC small breaker 2 is protected, prevent Only described breaker of plastic casing 3 is not sensitive enough;The cable peace of the header box of described breaker of plastic casing 3 mainly described in protection entirely Entirely, prevent from overloading or leaking electricity;Described fuse 4 is then for protecting output cable, due to the electric current and electricity of output cable Pressure is larger, it is necessary to which described fuse 4 carries out short-circuit protection;The described header box that such multi-stage protection just can be is in difference Transport current in the case of protection circuit.
