Abstract
The utility model discloses an intrinsically safe power supply module for a lithium battery. The intrinsically safe power supply module comprises a plurality of lithium batteries, a protective circuit board which is connected with a power output interface, and a lithium battery encapsulation box, wherein the protective circuit board is connected with the corresponding positive pole and negative pole of the lithium battery through conducting wires; and the lithium battery, the protective circuit board and the conducting wire are encapsulated in the lithium battery encapsulation box. The intrinsically safe power supply module for the lithium battery can meet the requirement of explosion protection. Compared with the intrinsically safe lithium battery, the intrinsically safe power supply module for the lithium battery reduces great cost, and has a smaller volume and stable and reliable voltage.
Description
Technical field
The utility model relates to a kind of lithium battery intrinsic safety electric source module, belongs to the explosion-proof technology field.
Background technology
At present, existing gas-fired equipment is operated in the hazardous area mostly, like 1 district, and 2 districts.During as power devices, generally is to be placed in the flame proof box with non-intrinsic safety lithium battery, satisfies requirement of explosion proof with the physical isolation mode.The flame proof box body is long-pending big, Heavy Weight, and cost is high; Flame proof box cavity volume is little, as increasing the flame proof cavity, then needs the thickness of more costs and increase flame proof box wall.Also have and use intrinsic safety lithium battery power devices, but the intrinsic safety lithium battery costs an arm and a leg, and battery capacity is less, mode of operation great majority be little power consumption mode, than greatly the time, then need higher cost to meet the demands like the external equipment power consumption.
Summary of the invention
The purpose of the utility model is the defective that overcomes prior art, provides that a kind of cost is low, volume is little and can satisfy the lithium battery intrinsic safety electric source module of requirement of explosion proof.
The technical scheme that realizes the utility model purpose is: a kind of lithium battery intrinsic safety electric source module; Comprise some joint lithium batteries and the protective circuit plate that is connected with power output interface; The protective circuit plate is connected with the corresponding both positive and negative polarity of lithium battery through lead; Comprise that also lithium battery waters the envelope box, described lithium battery, protective circuit plate and lead all water be enclosed in lithium battery water the envelope box in.
Further, described lithium battery waters the envelope box and is provided with the fixed installation ear.
Further; But the circuit of described protective circuit plate by over-current over-voltage protection branch road recovery temperature fuse, can recover fuse and Thermal Cutoffs is in series, described over-current over-voltage protection branch road is by three the series circuits that resistance form of a diode with parallel connection.
After having adopted technique scheme; The utility model all waters the element that can produce spark and is enclosed in lithium battery and waters in the envelope box, wholely forms intrinsic safety parts, can reach requirement of explosion proof; Compare with the intrinsic safety lithium battery, it is also less to have reduced very big cost and volume; The setting of fixed installation ear, it is convenient to make the utility model install, dismantle, change; The protective circuit plate has the effect of overvoltage, overcurrent and overheat protector, makes that lithium battery intrinsic safety electric source module stability is reliable.
Description of drawings
Fig. 1 is the structural representation of the lithium battery intrinsic safety electric source module of the utility model;
Fig. 2 is the B-B cutaway view of Fig. 1;
Fig. 3 is the circuit theory diagrams of the protective circuit plate of the utility model.
Embodiment
For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation,
Like Fig. 1, shown in 2; A kind of lithium battery intrinsic safety electric source module; Comprise some joint lithium batteries 1 and the protective circuit plate 2 that is connected with power output interface 4; Protective circuit plate 2 is connected with the corresponding both positive and negative polarity of lithium battery 1 through lead, comprises also that lithium battery waters to seal box 3, and lithium battery 1, protective circuit plate 2 and lead all water and be enclosed in lithium battery and water and seal in the box 3.Lithium battery waters envelope box 3 and is provided with fixed installation ear 3-1.
As shown in Figure 3; But the circuit of described protective circuit plate 2 by over-current over-voltage protection branch road recovery temperature fuse F1, can recover fuse F3 and Thermal Cutoffs F2 is in series, described over-current over-voltage protection branch road is by three the series circuits that resistance form of a diode with parallel connection.
The operation principle of the utility model is following:
The utility model all waters the element that can produce spark and is enclosed in lithium battery and waters in the envelope box 3, wholely forms intrinsic safety parts, can reach requirement of explosion proof, compares with the intrinsic safety lithium battery, and it is also less to have reduced very big cost and volume; The setting of fixed installation ear 3-1, it is convenient to make the utility model install, dismantle, change; Protective circuit plate 2 has the effect of overvoltage, overcurrent and overheat protector, makes that lithium battery intrinsic safety electric source module stability is reliable.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
