Description
Technical field
The utility model relates to a kind of detection alarm device, the detection alarm device that particularly uses in the transformer vacuum oil process.
Background technology
According to GB regulation, in the Repair of Transformer process, during the above oiling transformer of 35kV, need to vacuumize processing to its body and built-in electrical insulation, electric pressure difference, vacuum tightness require also different.When transformer vacuum oil, be all to judge the oil level position with hand in the past.Easily judgement is inaccurate with feel judgement position, often has very large error, and transformer oil is extracted out from vacuum pump, thereby damages oil filter; When oil level is too low, can cause secondary vacuum pumping, oiling.So both cause manpower financial capacity's waste, and can have certain potential safety hazard again.
Chinese patent CN202352454U discloses a kind of transformer vacuum oil device for preventing oil spilling, and this device is comprised of alarm and trigger controller, although played preventing oil spill, the effect of oil spilling alarm, can not observe oil level intuitively.
The utility model content
The utility model technical issues that need to address are to provide a kind of visual detection warning device that is applied to transformer vacuum oil, can truly reflect accurately main-transformer body level height, and reach the predetermined altitude alarm at oil level, stop the problems such as oil spilling that the oil level deviation brings or secondary vacuum pumping.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
transformer vacuum oil visual detection warning device, comprise alarm circuit, in alarm circuit, be connected in series with audible-visual annunciator and power module, the outside of transformer body also is provided with the transparent communicating pipe that two ends are connected with bottom part body and main body top respectively, described communicating pipe and the corresponding position of main body warning oil level are provided with the oil level display instrument, the two ends of oil level display instrument oil pipe are connected in communicating pipe by flange respectively, in described oil level display instrument oil pipe, be provided with magnetic ball float and the triggering node that is positioned at main body warning oil level position, described triggering node is connected in series in alarm circuit.
Principle of work of the present utility model is as described below:
When vacuumizing, because transformer bottom and top were communicated with communicating pipe, be equivalent to a linker, the pressure of outside communicating pipe and transformer inside is consistent, when vacuum oil the transformer interior oil can flow in outside communicating pipe and the oil level place in the same horizontal line, thereby realized that transformer oil level is visual.In communicating pipe top bodies warning oil level position, install the oil level display instrument additional and reflect oil level in good time, in oil level display instrument oil pipe, set up the magnetic ball float and trigger node by the setting height induction, thus the alerting signal of sending.
Improvement of the present utility model is: the input end of power module connects AC power, and the output terminal of power module connects rectification module, and the output terminal of rectification module is connected in series and forms alarm circuit with triggering node and audible-visual annunciator respectively.
Owing to having adopted technique scheme, the technical progress that the utility model is obtained is:
The utility model makes the inner oil level of transformer visual by law of connected vessels, the real-time height of oil level in true accurate reflection main transformer body vacuum oil process; And, when oil level reaches predetermined altitude, by the magnetic ball float, triggering the mode open alarm circuit of node, audible-visual annunciator sends alerting signal, thereby has avoided the problems such as oil spilling that the oil level deviation brings, secondary vacuum pumping.
The setting of rectification module in alarm circuit; can be used for AC power is converted to direct supply; thereby the current value while reducing the alarm circuit connection in circuit; can avoid audible-visual annunciator and oil level display instrument in circuit turn-on moment, to suffer the generation of heavy current surge phenomenon; effectively protect the safety of each components and parts in the alarm circuit, extended serviceable life of the present utility model.
The accompanying drawing explanation
Fig. 1: structural representation of the present utility model;
Fig. 2: the utility model circuit connection diagram.
Wherein: 1. communicating pipe, 2. oil level display instrument, 21. oil level display instrument oil pipes, 3. trigger node, 4. magnetic ball float, 5. audible-visual annunciator, 6. power module, 7. rectification module.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is done further to describe in detail:
Transformer vacuum oil visual detection warning device, as shown in Figure 1, comprise communicating pipe 1, oil level display instrument 2 and alarm circuit.Communicating pipe 1 is connected with transformer bottom and top, for the particular location that shows the transformer body oil level directly perceived.
Oil level display instrument 2 is arranged on communicating pipe and the corresponding position of main body warning oil level, comprises oil level index dial and oil level display instrument oil pipe 21, in oil pipe, is provided with magnetic ball float 4 and triggers node 3, and wherein oil level display instrument oil pipe is connected in communicating pipe by flange.
In alarm circuit, be connected in series with audible-visual annunciator 5, power module 6 and trigger node 3, the output terminal of power module also is connected with rectification module 7, for the AC rectification by input, is direct current, reduces the rush of current to audible-visual annunciator.In alarm circuit, the circuit connecting relation of each device as shown in Figure 2.
The utility model adopts law of connected vessels, utilize communicating pipe that transformer bottom and top are communicated with, during vacuum oil, the transformer interior oil can flow in outside communicating pipe, oil level in communicating pipe and the oil level place in transformer body in the same horizontal line, thereby realized that transformer oil level is visual.The oil level display instrument that install communicating pipe and main body warning oil level relevant position, for when oil level reaches predetermined altitude, the magnetic ballottement should trigger node, triggers the node closure, the alarm circuit conducting, audible-visual annunciator sends alerting signal.
