Abstract
The utility model relates to the air pressure type operation mechanism of the high voltage switch, comprising an independent compressed air source (1) and an independent air storage device (2). An inner air passage enclosed type air pressure controlling valve (3) is adopted, which decreases the air leakage and improves the job condition and the reliability of the work. The utility model uses the alternating current as well as the direct current, and has strong independence and adaptability and convenient use. Compared with the present air pressure operating mechanism, the utility model has no use of constructing and laying the air pipelines, is suitable for the large and medium size electric substation, and also is suitable for the high voltage switch and the composite apparatus with various voltage levels in the small size electric substations.
Description
The utility model relates to a kind of high-voltage switch gear vapour-pressure type operating mechanism.
Existing high-voltage switch gear vapour-pressure type operating mechanism generally includes an air pressure mechanism, single-stage or the pneumatic control valve of two-stage, a making electromagnet.Use the vapour-pressure type operating mechanism, need build an air compressor plant, and use pipeline, compressed air is delivered to each operating mechanism.
Because need to build necessary civil engineering facility and roughing-in such as air compressor plant and pipeline groove, cost is higher.In the occasion of the high-voltage switch gear that uses separate unit or negligible amounts, it is uneconomic using above-mentioned vapour-pressure type operating mechanism.Air pressure mechanism, pneumatic control valve and the making electromagnet of existing vapour-pressure type operating mechanism is that open type and apportion are arranged.Between air pressure mechanism and the pneumatic control valve, and between the step valve and secondary valve of pneumatic control valve, all carry out the outside with tracheae and connect, the gas leakage link is more.Because open type, condition of work is relatively poor, is subject to external environments influences such as dust and wind and rain, even causes moving malfunctioning, causes the accident.
The purpose of this utility model be to overcome existing above-mentioned shortcoming in the prior art and provide a kind of can reliably working and the vapour-pressure type operating mechanism of less expensive, the switchyard that not only can be used for many high-voltage switch gears also can be applicable to the occasion of the less even separate unit switch of number of switches.
Task of the present utility model is finished by following scheme: every operating mechanism has independently compressed air source and independently caisson.Simultaneously, air flue closed structure in multistage pneumatic control valve adopts avoids the outside tracheae between each step valve to connect.Each step valve of pneumatic control valve adopts coaxial arrangement, secondary valve pocket version in the outside of preceding step valve, and makes an outside sealed whole body.
Compared with prior art, the utlity model has following advantage:
1/ the utility model has independently compressed air source and independently caisson, so very strong independence is arranged.It does not rely on outside air compressor plant, thereby does not need the compressed air piping air feed yet, does not need heavy in section cable yet, as long as can normal operation input after general power line connects, uses very convenient.Be well suited for compact type substation and vast rural area electric substation.Also be applicable to big-and-middle-sized switchyard and electric substation.
2/ owing to need not build air compressor plant and relevant therewith facilities such as air duct groove, do not need to lay air duct yet, do not have the civil engineering workload, and cost is lower, has saved floor space simultaneously.
3/ owing to saved air compressor plant and steam line, and air flue enclosed type pneumatic control valve in adopting, and significantly reduced gas leakage, avoid the Fraquent start of air compressor machine, improve condition of work simultaneously, thereby improved the reliability of action, and prolonged the useful life of equipment.
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is a kind of structural representation of the present invention.
As seen from Figure 1, compressed air source (1) produces the compressed air of required pressure, enters a gas tank (2).When closing operation, have pneumatic control valve (3) action of making electromagnet, make the compressed air in the gas tank (2) enter cylinder (4) by control valve (3), the piston (5) in the cylinder is moved upward, finish feed motion.
(6) be the closing by hand lever.For reducing the gas leakage link, the air inlet non-return valve (7) of gas tank is arranged in gas tank inside, and makes an integral body with gas tank.
Compressed air source (1) can be the logical air compressor of a Daepori, and its pressure adjustable range can be at the about 4.2-5.5kgf/cm of 412kPa-539kPa(
2) between.The volume of gas tank (2) should suitably be selected, and allows mechanism to close a floodgate continuously for several times.
Fig. 2 is pneumatic control valve structural representation of the present utility model.
As seen from Figure 2, pneumatic control valve is a kind of interior air flue enclosed type two-stage control valve. Its design feature is: secondary valve is the outside that is enclosed within one-step valve, and with the making electromagnet coaxial arrangement in the valve body (17) of a sealing. When closing coil (8) excitation, moving (9) unshakable in one's determination move downward. One-step valve push rod (10) is pressed towards down, open the valve disc (16) of one-step valve, compressed air enters valve pocket (18) from the pipeline (19) that connects gas tank, enter the valve pocket (11) of secondary valve by the space between push rod (10) and the secondary valve disc bar (13), secondary valve piston (12) is moved downward, open secondary valve disc (15). Compressed air enters air chamber (14), enters cylinder (4) by hole (20).
Can be connected with flange between electromagnet and the control valve. Electromagnet can exchange, and also can be direct current. Like this, just make the utility model that bigger adaptability and flexibility are arranged.
Whole operating mechanism is protective construction, is contained in the casing, can avoid the harmful effect of environment.
Gas tank also can be arranged in the casing outside.
The utility model is applicable to high-voltage switch gear and the combined electrical apparatus of various electric pressures. Interior air flue enclosed type pneumatic control valve provided by the utility model also can be applicable to other field.
