Description
Technical field
The present invention relates to a kind of transformation Buchholz relay corollary apparatus, particularly a kind of transformer Buchholz relay intelligence means of deflation.
Background technology
The venting work of existing main transformer Buchholz relay, need manually carry out, when particularly there is gas or break down in main transformer inside, often can not exit in time, had a strong impact on the safe operation of transformer, and above situation occur time, need send someone in time, send special train to be exitted to scene, sometimes also need to work on charged transformer of climbing up operation, the livewire work of particularly ascending a height at scenes such as the bad weather such as thunderstorm, strong wind and far away and remote transformer station, power plant has more danger.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and provide one to carry out intelligent automatic deflation to Buchholz relay, without manual operation, the transformer Buchholz relay intelligence means of deflation of the safe operation of powerful guarantee main transformer and personal safety.
A kind of transformer Buchholz relay intelligence means of deflation, described device includes a photosensitive control room and control module, in photosensitive control room, be provided with laser instrument, photosensitive probe, shading float and float gag lever post, photosensitive control room is arranged on Buchholz relay top, the inner chamber in photosensitive control room communicates with gas circuit breaker inner chamber, shading float is sleeved on float gag lever post and can on float gag lever post, slides up and down, float gag lever post is suspended on the top in photosensitive control room, the length of float gag lever post extend into the length that is greater than a shading float under the normal pasta of Buchholz relay, the upper position place that approaches Buchholz relay in photosensitive control room is provided with photosensitive probe and the laser instrument of horizontal linear configuration in opposite directions, described photosensitive probe and laser instrument are divided into the both sides of shading float and depart from float gag lever post, shading float blocks photosensitive probe at transformer Buchholz relay during in normal work and receives the laser beam that laser instrument sends between photosensitive probe and laser instrument, in the time there is gas in transformer Buchholz relay, shading float declines and makes photosensitive probe can receive the laser of laser instrument, top in photosensitive control room leads to blast pipe, pressure-releasing electromagnetic valve is installed on blast pipe, described control module includes photo controller and control circuit, pressure-releasing electromagnetic valve is normally off at transformer Buchholz relay during in normal operation.
Transformer Buchholz relay of the present invention intelligence means of deflation, pressure-releasing electromagnetic valve is normally off at transformer Buchholz relay during in normal operation. Transformer Buchholz relay, in the time of normal operation, is full of oil in Buchholz relay, because laser beam is blocked by shading float, photosensitive probe does not receive laser, and therefore photo controller is not worked. In the time there is gas in Buchholz relay, gas can rise oil level is declined, and shading float declines thereupon, laser beam irradiation is to photosensitive probe, start photo controller, open pressure-releasing electromagnetic valve by photo controller control by control circuit, exit, along with the carrying out of deflation course, Buchholz relay oil level rises, and shading float covers photosensitive probe again, and photo controller is closed, controlled device is also closed simultaneously, automatic deflation end-of-job.
Described control circuit includes the time relay, the Control time relay action of photo controller connect hours.
The effect of setting up the time relay in control circuit is; in the time there is catastrophe failure in main transformer contingency; the gas producing can impact Buchholz relay baffle plate together with oil stream, makes heavy watt of protection action of main transformer, jumps main transformer switch; thereby the further expansion of Accident prevention; now as by gas discharging, may affect gas and oil stream impact baffle plate, may cause main transformer switch not trip and make accident continue the consequence expanding; and gas time delay discharge does not affect main transformer safe operation.
Described shading float is hollow float.
Adopt hollow float can alleviate the weight of float.
In sum, the present invention's following advantage compared to existing technology:
Transformer Buchholz relay intelligence means of deflation of the present invention, without special staff, Buchholz relay is carried out to venting work, for guarantor's body, guarantor's power grid security important in inhibiting, this project is domestic blank, can also greatly save manpower, material resources as put into operation.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in more detail.
Embodiment 1
A kind of transformer Buchholz relay intelligence means of deflation as shown in Fig. 1-6, described device includes a photosensitive control room 1 and control module, in photosensitive control room, be provided with laser instrument 2, photosensitive probe 3, shading float 4 and float gag lever post 5, photosensitive control room is arranged on Buchholz relay top, the inner chamber in photosensitive control room communicates with gas circuit breaker inner chamber, shading float is sleeved on float gag lever post and can on float gag lever post, slides up and down, float gag lever post is suspended on the top in photosensitive control room, the length of float gag lever post extend into the length that is greater than a shading float under the normal pasta of Buchholz relay, the upper position place that approaches Buchholz relay in photosensitive control room is provided with photosensitive probe and the laser instrument of horizontal linear configuration in opposite directions, described photosensitive probe and laser instrument are divided into the both sides of shading float and depart from float gag lever post. when normally working, transformer Buchholz relay is full of oil in Buchholz relay, shading float is between photosensitive probe and laser instrument, and because laser beam is blocked by shading float, photosensitive probe does not receive laser beam, therefore photo controller is not worked, and is normally off when pressure-releasing electromagnetic valve normally moves. when transformer Buchholz relay 8 is interior while there is gas, because declining, pasta cause shading float to decline, the laser of laser instrument transmitting can be irradiated on photosensitive probe, make photosensitive probe receive the laser of laser instrument, thereby the photo controller in photosensitive control room is opened, control time time-delay relay is opened pressure-releasing electromagnetic valve by the delay time of setting, exit, pressure-releasing electromagnetic valve 6 is arranged on drawing on blast pipe 7 of top, photosensitive control room, described control module includes photo controller and control circuit, pressure-releasing electromagnetic valve is normally off at transformer Buchholz relay during in normal operation. described shading float is hollow float. described control circuit includes the time relay, the Control time relay action of photo controller connect hours.
It is same as the prior art that the present embodiment is not stated part.
