The explosion-proof UPS power supply is used for providing the uninterruptible power supply and the UPS power supply to underground monitoring devices. The explosion-proof UPS power supply has the advantages of explosion-proof property, high output voltage, long-term power supply, and so on.

Description

Colliery flame proof ups power

Technical field

The utility model relates to a kind of ups power, specifically a kind of colliery that can power for a long time flame proof ups power.

Background technology

The application of the control under the coal mine, watch-dog and system is more and more, these equipment and system can not sudden power cut off the power supply with long-time, though there is stand-by power supply the down-hole, when all power cut-offs, watch-dog is out of service, and the equipment and the personnel in colliery are caused great potential safety hazard.Existing ups power explosion-proof performance is poor, and voltage is generally AC220V.Operating time is short, general about 2 hours, can not be used under the coal mine.

Summary of the invention

Goal of the invention of the present utility model is poor at existing ups power explosion-proof performance, and voltage is low, the operating time is short, can not be used for the deficiency under the coal mine, provide a kind of explosion-proof performance good, can power the colliery that output voltage is high flame proof ups power for a long time.

Realize the foregoing invention purpose by the following technical solutions: a kind of colliery flame proof ups power, comprise casing and place the interior circuit of casing, its circuit comprises input isolating transformer T1, master board, storage battery, voltage stabilizing, inversion, sampling filter transformer T3, output isolation transformer T2, it is characterized in that: described casing adopts the explosion-proof chamber body structure of two upper and lower settings, and the input of input isolating transformer T1 is connected with the AC660V power supply, and output is connected with master control borad; Master control borad is connected with storage battery, is connected with voltage stabilizing, inversion, sampling filter transformer, and T2 is connected with output isolation transformer.T2 output AC660V powers to external equipment.

Adopt technique scheme, compare with existing ups power, the utility model is supplied with down-hole AC660V low-power equipment power supply uses such as power-off protector with voltage process step-down, the rectification of input, the processing back output AC660V voltage that boosts.Be used for providing uninterrupted power supply and ups power to downhole monitoring equipment (power is generally below 150W).Have advantages such as explosion-proof, output voltage high (more than 5 hours) for a long time power supply, be applicable in the hazardous environment of damps such as gas, coal dust are arranged under the coal mine.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Referring to Fig. 3, Fig. 4, two explosion-proof chamber body structures are adopted with the casing of flame proof ups power in the colliery, the explosion-proof chamber that is positioned at the top of casing also is a wire connection cavity 1, is provided with four binding posts 3 in this chamber, and rear side is established three outlet mouths 4, one is electric power incoming line, two power outlets.Another explosion-proof chamber 2 is positioned at the below of wire connection cavity 1.Referring to Fig. 1, Fig. 2, circuit of the present utility model is made of input isolating transformer T1, master board, storage battery, voltage stabilizing, inversion, sampling filter transformer T3, output isolation transformer T2.The input of input isolating transformer T1 is connected with the AC660V power supply, and output is connected with master control borad; Master control borad is connected with storage battery, is connected with voltage stabilizing, inversion, sampling filter transformer, and T2 is connected with output isolation transformer, and output isolation transformer T2 output AC660V powers to external equipment.

Operation principle of the present utility model and process:

The AC660V supply voltage is exported AC220V voltage after the AC660V/220V transformer T1 step-down in power supply box, enter 6 and 8 pin of master board CH4, output DC12V charges a battery to export to transformer T3 step-down after 1 and 2 pin of X8 are exported to rectifier bridge D1 rectification after the 4A/4B coil filtering of the X8 of T3 through master board, through master board 12V is reverse into to exchange simultaneously and rises to AC220V to output AC220V/660V step-up transformer T2 for transformer T3, transformer output AC660V powers to external equipment; After power failure, directly export 12V by storage battery, through master board 12V is reverse into to exchange and rises to AC220V to output AC220V/660V step-up transformer T2 for transformer T3, transformer output AC660V powers to external equipment.
