In the utility model, multiple switching mode auxiliary power circuit plate is arranged in closed left chamber 402, the electromagnetic interference for the control circuit board in right chamber 403 can be effectively reduced, consider the needs that switching mode auxiliary power circuit plate dispels the heat simultaneously, the top of left chamber 402 and bottom all offer ventilation hole 402, for the heat loss through convection of left chamber 402 switching mode auxiliary power circuit plate.System, control circuit plate in right chamber 403 is because power consumption is little, therefore right chamber 403 is designed to be almost hermetic form except the cable-through hole for control signal cable, both be beneficial to the anti-electromagnetic interference capability of the system, control circuit plate in right chamber 403, contribute to again the ability of the protection to dust.The breach 406 for exposing control interface that right chamber 403 cover plate is offered, by the system parallel operation control interface in chamber to exposing outside, these interfaces exposed belong to safety circuit in safety, can be open to user.When user is as needed parallel operation control cables at the scene between connected system rack, open the behind the door outer of rack, by the control cable cable-through hole 600 of parallel operation control cables through rack front lower portion component cavity 100, along the routing path that rack column is preset, directly parallel operation control cables can be inserted on the system parallel operation control interface in right chamber 403, obviously, the utility model design is by the installation and maintenance at the scene of great convenience system.
With reference to Fig. 6, external door is provided with external control element chamber 500, external control element chamber 500 is provided with safety cover plate 502 and monitor component, and monitor component comprises display screen, plastic rubber panel, finger-board and supervisory circuit plate 501 and communication card.The dangerous circuit of safety that safety cover plate 502 can not directly touch on supervisory circuit plate 501 mainly for the protection of user, interface supervisory circuit plate 501 belonging to safety safety circuit exposes, as communication interface, dry contact control interface etc. by safety cover plate 502.The utility model has the advantage of that the external door only opening rack just can connect the external monitor-interface of energy-storage system, when user is as needed the control of the external monitor-interface of connected system at the scene and telecommunication cable, open the behind the door outer of rack, by the control cable cable-through hole 600 of above-mentioned monitor-interface cable through rack front lower portion component cavity 100, along rack column up and along on external door preset routing path, can be directly inserted in by above-mentioned cable on the corresponding externally monitor-interface of supervisory circuit plate 501, above-mentioned design is by the installation and maintenance at the scene of great convenience system.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
