Abstract
The utility model relates to a back-up safety power supply for oil field operation. Because a ballast and a boost capacitor are matched and connected with the output terminal of the back-up safety power supply for oil field operation, the output impulse current is enhanced, the back-up safety power supply for oil field operation can be matched and connected with the 24V accumulator of a working machine, and the disadvantage that the existing inverter power supply has difficulty in starting the metal halide lamp is overcome. | The strong luminous problem in the areas where the network and the power supply are not provided and the operation is carried out is solved. At the same time, the power supply id provided with an organic inner cell, the lighting can not be uninterruptible when the outer cell is changed.
Description
The utility model belongs to power-supply device.
Existing oil field operation power supply is an electrical network, i.e. power supply by the power transmission and transformation net, this supply power mode brings many inconvenience for the oil field operation, sometimes need set up long temporary line, dc inverter, storage battery on the working rig can be changed into the 220V alternating current, but present this inverter current can not satisfy the heavy current pulse of metal fontanelle compound lamp when starting, and existing large power inverter power source needs to connect with the 48V DC power supply.
The purpose of this utility model is to realize a kind of inverter-oil field operation reserve safety power supply that adapts to oil field field work, the heavy current pulse when making it can satisfy the startup of metal fontanelle compound lamp, and can be matched with the 24V DC power supply of oil field operation machine.Be the oil field field mobile operation illuminalive power-supply condition of providing convenience.
Oil field operation reserve safety power supply of the present utility model is boosted through amplification by signal in a 50HZ/ of the oscillating circuit output arteries and veins of second, and the dc inversion that makes 24V is the alternating current of 220V.For satisfying the characteristics of the big current start of metal fontanelle compound lamp, be connected in series a ballast at 220V alternating current output.This ballast has a centre cap, and tap and another termination one electric capacity of output owing to the boosting of capacitor discharge and ballast, can start metal fontanelle compound lamp when metal fontanelle compound lamp starts smoothly.Continuous illumination when changing battery for making, this power supply is provided with storage battery in the machine.Whole machine installation is in the metal shell of a band louvre.
The utility model has overcome oil field field work and has used inverter to be difficult to the defective that metal chimney thing lamp is started, and has solved the floodlighting problem of operation under no electrical network electricity situation, and operation provides convenience outside the oil supply field.Be provided with self-contained battery simultaneously, when changing external storage battery, can tie up illumination.Whole machine installation has to loose one to be held in the metal shell in hole, transports easy to carry.
Description of drawings: Fig. 1 is an oil field operation reserve safety power supply schematic diagram, wherein, and 1. oscillating part, 2. amplify the inversion part, 3. boost part, 4. ballast of ballast, 5. ballast centre cap, 6. boost capacitor, 7. metal fontanelle compound lamp output, 8. alternating current 220V output, 9, public output, 10. storage battery in the machine, 11. external storage batterys.Fig. 2 is an oil field operation reserve safety power supply outline drawing, wherein, and 12. housings, 13. relay indicating lights, 14. louvres, 15. switches.
The oil field operation reserve safety power supply that now will realize 500VA is that example is done to assemble one by figure (1) (2) and be input as direct current 24V to describe in detail, is output as 220V and exchanges.The inverter of 500VA, its assembly and adjustment method is identical with existing inverter, and its different piece is for being provided with inversion boosting part (3), and ballast (4) is wound on the iron core that sectional area is 30mm * 40mm with the enamelled wire of diameter 1mm.Around 600 circles.At 300 circle places as centre cap (5), the AC capacitor that boost capacitor (6) is got 8MF/600V, (6) metal chimney thing lamp output can directly connect the metal fontanelle compound bulb of a 175W.Because the interaction of ballast (4) and electric capacity (6) makes pulse up to tens of amperes, metal fontanelle compound bulb is lighted, this power supply has 220V to exchange output (8) simultaneously, to satisfy the electricity consumption needs of other electrical appliances, external direct current power supply (11) can be connected on the working rig storage battery of 24V, the available 24V of internal memory storage battery (10), the NI-G rechargable battery of 9AH.Complete machine can be contained in the metal shell (12) of 35 * 40 * 20cm band louvre (14).
Claims (4)
1, a kind of oil field operation reserve safety power supply is characterized in that output series connection ballast (4) and shunt capacitor (6) at power supply.
2,, it is characterized in that capacitor (6) is connected on the centre cap (5) of ballast (4) according to the said oil field operation reserve of claim 1 safety power supply.
3,, it is characterized in that being equipped with storage battery (10) in the machine according to the said oil field operation reserve of claim 1 safety power supply.
4,, it is characterized in that being installed in the metal shell (12) that has louvre (14) according to the said oil field operation reserve of claim 1 safety power supply.
