Abstract
The utility model provides a cabinet for a photovoltaic grid-connected inverter. The cabinet comprises a box body; the box body is provided with a front door body and a rear door body; a clapboard is arranged at the vertical position of the box body in a longitudinal direction; a separating board is arranged between the clapboard and the front door body; a space between the front door body and the clapboard is separated into a control chamber and an input and output switch chamber by the separating board; spaces between the rear door body and the clapboard are voltage regulation chambers; and therefore, the control chamber is used for placing a control circuit board, the input and output switch chamber is used for placing a circuit breaker and a contactor, the voltage regulation chambers are used for placing an insulated gate bipolar transistor (IGBT) module and a transformer, heat generated by the IGBT module and the transformer is pumped upwards by a radiator fan and discharged through an exhaust port, and moreover, electromagnetism can be transmitted to underground under the action of grounding of a magnetic transmitting port, so that the phenomenon of a large number of electromagnetic waves are stored in the box body is avoided, and the effects of independent work and noninterference of each main circuit part are effectively achieved.
Description
Technical field
The utility model relates to the parallel network circuit cabinet body structure, relate in particular to a kind of about photo-voltaic power supply to the be incorporated into the power networks photovoltaic combining inverter cabinet of aspect of electrical network.
Background technology
Traditional photovoltaic combining inverter electronic box cabinet mainly is that the stake body by frame structure is main; Surface at support is provided with shell attractive in appearance again; Support can be adjusted the installation site flexibly in response to the size of each installing component, but just the inner structure part of whole box body occurs in a support, can watching, yet in electronic box; Transformer is main heat generating components, also is the critical piece of making electromagnetic interference; Microcircuit control board in the middle of causing extremely easily, disconnect etc. receive the interference of temperature and electromagnetism, and the hot gas of temperature rises in addition, and the air-flow in the case can flow mussily; Improve the interference effect of electromagnetism more; Therefore, how to overcome the problem of dispelling the heat and doing interference, optimal method of operation is in the electronic box body, compartment to be set; Carry out the apportion ranking to each parts, each have independently chamber body.
Summary of the invention
The utility model provides a kind of photovoltaic combining inverter cabinet; Through three chamber bodies such as control room, input chamber and voltage-regulation chamber are set respectively in cabinet; Open each critical piece is independently divided effectively; And, through to casing arranged outside magnetic conduction interface, be delivered to the electromagnetism that produces in the device underground.
Therefore; The utility model comprises casing; Said casing is provided with Qianmen body and back door body, and vertical upright position of said casing is provided with a dividing plate, is provided with demarcation strip between said dividing plate and the Qianmen body; Demarcation strip is control room and input chamber with the separated by spaces between Qianmen body and the dividing plate, and the space between said back door body and the dividing plate is the voltage-regulation chamber.
The by-level position of said voltage-regulation chamber is provided with dismountable waffle slab, is provided with the aspirating hole that is used to install radiator fan in the said waffle slab.
The top of said voltage-regulation chamber is provided with exhaust outlet.
The bottom of said casing is provided with the Ci Kou that crosses of extradition electromagnetism ground connection.
Therefore, the beneficial effect of the utility model is: vertical upright position of said casing is provided with a dividing plate, is provided with demarcation strip between said dividing plate and the Qianmen body; Demarcation strip is control room and input chamber with the separated by spaces between Qianmen body and the dividing plate; Space between said back door body and the dividing plate is the voltage-regulation chamber, and therefore, the control room is used to place control circuit board; The input chamber is used to place circuit breaker and contactor; IGBT module and transformer are placed in the voltage-regulation chamber, and the heat that IGBT module and transformer are produced up extracts through heat emission fan and from the exhaust outlet discharge, the ground connection effect of crossing the magnetic mouth in addition also can be the electromagnetism extradition to underground; Avoid storing a large amount of electromagnetic waves in the casing, effectively realize working alone and interference-free effect of each main circuit parts.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Embodiment
In conjunction with accompanying drawing the utility model is further described; As shown in Figure 1, casing 1 is provided with Qianmen body 2 and back door body 3, and Qianmen body 2 is arranged on casing 1 forwardly; Back door body 3 is arranged on casing 1 at the rear portion; Vertical upright position of said casing 1 is provided with a dividing plate 4, is provided with demarcation strip 5 between said dividing plate 4 and the Qianmen body 2, and demarcation strip 5 is control room 21 and input chamber 22 with the separated by spaces between Qianmen body 2 and the dividing plate 4; Space between said back door body 3 and the dividing plate 4 is voltage-regulation chamber 31; What the bottom of said casing 1 was provided with extradition electromagnetism ground connection crosses magnetic mouth 11, and the by-level position of said voltage-regulation chamber 31 is provided with dismountable waffle slab 32, and purpose is to separate IGBT module and transformer neatly; Be provided with the aspirating hole 33 that is used to install radiator fan in the said waffle slab 32, the top of said voltage-regulation chamber 31 is provided with exhaust outlet 34.
Therefore, said control room 21 is used to place control circuit board, and said input chamber 22 is used to place circuit breaker and contactor; IGBT module and transformer are placed in said voltage-regulation chamber 31; And the heat that IGBT module and transformer are produced is up to extract and discharge from exhaust outlet 34 through heat emission fan, and certainly, radiator fan also can be installed in and directly extract hot gas in this exhaust outlet 34; In addition; Cross the ground connection effect of magnetic mouth 11 and also can avoid storing a large amount of electromagnetic waves in the casing, effectively realize working alone and interference-free effect of each main circuit parts the electromagnetism extradition to underground.
