Abstract
The utility model relates to a UPS battery protective device. Commercial electricity is connected with a switch cabinet and is connected with a UPS in a circuit after flowing through the switch cabinet; UPSs are connected with electric power equipment and output power supply to the connected electric power equipment; the UPSs are simultaneously connected with battery packs; each battery pack is composed of a plurality of series connected batteries; and any two batteries of each battery pack is series connected with an air switch or a fuse. According to the utility model, the air switch or the fuse is additionally arranged at the connection position of any two batteries of each pack of batteries so that when a short circuit fault occurs in a battery, the air switches or the fuses are automatically cut off, thus burning loss of the whole packs of batteries are avoided, the UPSs are prevented from impact of heavy current, no other adverse influences are generated, the operation is stable and reliable, and the device overall safety is improved.
Description
Technical field
The utility model belongs to field of electrical equipment, relates to uninterrupted power supply UPS equipment, especially a kind of UPS battery protective device.
Background technology
Current; power system device adopts uninterrupted power supply UPS equipment to be powered more, and UPS can play to mains supply " purification " effect, has overload protection function and stronger antijamming capability simultaneously; power quality is reliable and stable, realizes noiseless, voltage stabilizing, frequency stabilization power supply to load.The UPS operation principle: when power supply is normal, civil power is charged to storage battery by rectifier, after civil power disturbs by the preliminary voltage stabilizing of automatic voltage regulator, absorption portion electrical network simultaneously, more directly gives the load power supply by the bypass change over switch.Now, storage battery is in charged state, proceeds to floating charge state until storage battery is full of.When occurring having a power failure, storage battery is discharged, and produces the alternating current of 220V, 50Hz through the inverter conversion, to the load power supply.Wherein, battery pack is inner is the series connection of polylith battery, when appearring in single battery for a certain reason, burning or short circuit can cause the damage of whole Battery pack, even produce fire or blast, there is potential safety hazard, the impulse current that short circuit simultaneously produces also can cause damage to UPS equipment, produces larger economic loss, and brings a lot of inconvenience to the repairing of UPS and the recovery of power supply.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of design science, simple in structure, practical, safe and reliable UPS battery protective device are provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of UPS battery protective device; civil power connecting switch cabinet by after switch cubicle, by circuit, being connected with a UPS; UPS all connects power equipment by circuit and powers to connected power equipment output; described UPS is connected with a battery pack simultaneously; battery pack is comprised of a plurality of batteries that are connected in series, and it is characterized in that: between any two batteries of described battery pack, be connected in series an air switch or fuse.
And, interval a plurality of air switches that have been installed in series in described battery pack.
And described switch cubicle connects the multichannel civil power.
Advantage of the present utility model and good effect are:
The utility model installs an air switch or fuse additional in any two battery junctions of every Battery pack, when short trouble appears in cell circuit, sky is held or fuse can disconnect rapidly automatically, thereby avoid the scaling loss of whole Battery pack and the impact of electric current to UPS greatly, and can not produce other harmful effects, stable and reliable operation, the lifting means overall security.
The accompanying drawing explanation
Fig. 1 is application circuit schematic diagram of the present utility model;
Fig. 2 is the utility model electrical block diagram.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of UPS battery protective device; as shown in Fig. 1 to 2; civil power A road and civil power B road be connecting switch cabinet by after switch cubicle, being connected with a UPS by input circuit respectively respectively; UPS all connects power equipment by circuit and powers to connected power equipment output; described UPS is connected with a battery pack simultaneously, and battery pack is comprised of a plurality of batteries that are connected in series 1.
Wound of the present utility model is first put and is:
Be connected in series an air switch or fuse 2 between any two batteries of described battery pack, while being short-circuited, can cut off in time battery circuit, guarantee safety.
In order to promote the reliability of protector, shown in interval a plurality of air switches that have been installed in series in battery pack.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
