Abstract
The invention relates to a transformer body gas relay with an existing gas detection function. A light source emitter is arranged on an observation window on one side, and a light source receiver is arranged on an observation window on the other side; an output end of the light source receiver is connected with one end of a photoelectric conversion module; the other end of the photoelectric conversion module is connected with an alarm module; the light source receiver can receive light emitted by the light source emitter when gas exists in the gas relay. According to the transformer body gas relay, an integral judgment process is still based on the structure in the prior art, and no major change is required during improvement; the transformer body gas relay is easy and convenient to operate, has strong anti-interference capacity and can quickly learn the reasons of faults.
Description
Technical field
The invention belongs to the transformer body Buchholz relay and deposit gas detection technique field, especially a kind of have a transformer body Buchholz relay of depositing the gas measuring ability.
Background technology
The transformer body Buchholz relay is a kind of important protection component of reflection transformer body fault, it is contained on the conservator and the pipeline between fuel tank of transformer, its action is posted a letter may two kinds of reasons, a kind of is that transformer body fault aerogenesis generation oil stream impact, gas accumulates in relay, causes float or baffle plate action; Another kind of reason is the fault of relay own, as the damage of glass tongue tube etc.When reality is used, when Buchholz relay action is posted a letter, operating personnel only could determine and move the reason of posting a letter by the closely range estimation of observation window on transformer body, and this exists great potential safety hazard, has also increased the time of fault eliminating.Therefore, how to determine rapidly its reason of posting a letter after transformer has the Buchholz relay of carrying action, become the key issue that the electricity operator needs solution badly.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide strong a kind of of handling safety, antijamming capability to there is the transformer body Buchholz relay of depositing the gas measuring ability.
The technical scheme that the present invention takes is:
A kind of have a transformer body Buchholz relay of depositing the gas measuring ability, comprise Buchholz relay, the two ends of this Buchholz relay are communicated with respectively transformer body and conservator, both sides at Buchholz relay are equipped with observation window, it is characterized in that: at the unilateral observation window, one light source emitter is installed, at the opposite side observation window, one light source receiver is installed, the output of this light source receiver connects an end of a photoelectric conversion module, the other end of this photoelectric conversion module connects an alarm module, described light source receiver can receive the light of described light source emitter emission when Buchholz relay internal memory gas.
And, in the upper end of unilateral observation window, one light source emitter is installed, a light source receiver is installed in the lower end of opposite side observation window.
And, series connection one amplification module between described photoelectric conversion module and alarm module.
And described alarm module is used light-emitting diode.
Advantage of the present invention and good effect are:
In the present invention, light source emitter and light source receiver are installed respectively on the observation window of Buchholz relay both sides, light source emitter and light source receiver are obliquely installed, when relay is full of oil, the light of light source emitter emission produces refraction in oily medium, can't be received by the light source receiver, follow-up alarm module attonity, when relay is deposited gas, the refraction angle of light diminishes, make the light source receiver receive light signal, this light signal is transformed into the signal of telecommunication by photoelectric conversion module, again after amplification module amplifies, finally excite the lumination of light emitting diode in alarm module, operating personnel are got information about in Buchholz relay and deposited gas, it is basis that whole deterministic process still be take the structure of prior art, during improvement without larger change, and easy and simple to handle, antijamming capability is strong, can learn fast the reason of fault.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the trend of the light signal of the light source emitter of the Buchholz relay in Fig. 1 while being full of oil;
Fig. 3 is the trend of the light signal of the light source emitter of the Buchholz relay in Fig. 1 while being full of oil.
Embodiment
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A kind of have a transformer body Buchholz relay of depositing the gas measuring ability, as shown in Figures 1 to 3, comprise Buchholz relay 3, this Buchholz relay is connected on the pipeline 2 between transformer body 1 and conservator 7, the observation window 6 of protected lid 4 protections is installed in the both sides of Buchholz relay, innovation of the present invention is: at the unilateral observation window, one light source emitter 5 is installed, at the opposite side observation window, one light source receiver 9 is installed, the output of this light source receiver connects an end of a photoelectric conversion module, the other end of this photoelectric conversion module connects an alarm module, described light source receiver can receive the light of described light source emitter emission when Buchholz relay internal memory gas.
In the present embodiment, in the upper end of unilateral observation window, one light source emitter is installed, a light source receiver is installed in the lower end of opposite side observation window.Series connection one amplification module between described photoelectric conversion module and alarm module.Described alarm module is used light-emitting diode.
The course of work of the present invention is:
1. when Buchholz relay is full of oil, as shown in Figure 2:
The light signal that light source emitter 5 sends is injected in Buchholz relay with certain angle, because the density of oily medium 8 is greater than air, so light signal is according to the deflection than wide-angle has occurred shown in arrow in figure, make the light source receiver can't receive this signal, follow-up modules no signal, light-emitting diode is failure to actuate.
2. depositing gas when Buchholz relay is, as shown in Figure 3:
The light signal that light source emitter 5 sends is injected in Buchholz relay with certain angle, the density of gas 10 is close to air, so light signal is according to basic linear transmission shown in arrow in figure, the light source receiver receives this signal, follow-up modules moves successively, the light-emitting diode action, the alert failure cause.
In the present invention, light source emitter and light source receiver are installed respectively on the observation window of Buchholz relay both sides, light source emitter and light source receiver are obliquely installed, when relay is full of oil, the light of light source emitter emission produces refraction in oily medium, can't be received by the light source receiver, follow-up alarm module attonity, when relay is deposited gas, the refraction angle of light diminishes, make the light source receiver receive light signal, this light signal is transformed into the signal of telecommunication by photoelectric conversion module, again after amplification module amplifies, finally excite the lumination of light emitting diode in alarm module, operating personnel are got information about in Buchholz relay and deposited gas, it is basis that whole deterministic process still be take the structure of prior art, during improvement without larger change, and easy and simple to handle, antijamming capability is strong, can learn fast the reason of fault.
