Description
Technical field
The utility model relates to technical field of electrical equipment, is specifically related to a kind of screen cabinet for the online discharge system of storage batteries of transformer substation.
Background technology
At present, power industry generally adopts " load type " discharge technology to carry out storage battery checking discharge test, finds out the problem that batteries and cell exist.In practice process, find that the method exists the shortcomings such as complicated operation, workload are large, heating potential safety hazard.
But, no matter adopt electrothermal device or active inversion electric discharge device to carry out storage battery I
10discharge test, batteries must depart from DC bus, is substituted by standby battery group.The in the situation that of only having a group storage battery group in station, in core discharge capacitor, once there is the faults such as commercial power interruption, batteries can not provide back-up source and bring potential safety hazard to DC bus in time.
In screen cabinet, be provided with a lot of control components and parts and circuit, in the process of work, control components and parts in screen cabinet can send larger heat, if heat distributes not in time, temperature rise in screen cabinet causes the malfunctioning of control system, not only can affect the normal operation performance of equipment, and put aside for a long time heat and can bring larger potential safety hazard to components and parts and circuit in screen cabinet.
Therefore, how to solve and pass the slow deficiency of traditional screen cabinet heat radiation, with the normal operation of Guarantee control system, become those skilled in the art's technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of screen cabinet for the online discharge system of storage batteries of transformer substation, solves the problem of existing screen cabinet heat radiation, and simple in structure, cost is low, is convenient to apply on a large scale.
In order to achieve the above object, the utility model is achieved through the following technical solutions: a kind of screen cabinet for the online discharge system of storage batteries of transformer substation, be characterized in, and comprise:
Cabinet;
Be arranged on front panel, left plate, right plate, back door, base and upper cover on cabinet;
Be arranged on the central dividing plate between front panel and back door;
On described, cover and be provided with louvre;
Described central dividing plate is used for installing electric elements.
Described back door adopts two-sided to opening structure.
Described back door is provided with air inlet.
On described, cover and be provided with fan installing hole.
Described front panel adopts detachable closing plate structure.
Described front panel adopts rotary type structure.
Described left plate and right plate adopt live body formula structure.
Displaying Meter and control button are installed on described front panel.
Described central dividing plate upper end is provided with wire casing.
A kind of screen cabinet for the online discharge system of storage batteries of transformer substation of the utility model compared with prior art has the following advantages: air inlet and exhaust outlet are set, reach the effect of separate ventilation in screen cabinet, play the effect that reduces screen in-cabinet temperature; Front panel adopts detachable or rotary type, realizes quick, reliable closed colleague, and in the time of screen cabinet outlet fault, maintenance personal can detect the operating state of the interior electric elements of screen cabinet online, has greatly facilitated the investigation processing of fault.
