Abstract
The invention discloses a sheathed thermocouple for an explosion-proof transformer, and relates to a temperature sensing device. The sheathed thermocouple for the explosion-proof transformer comprises an outgoing line hole locking nut, a terminal block, a wiring porcelain plate, a protecting tube, an insulating porcelain tube, a first thermocouple wire and a second thermocouple wire, the insulating porcelain tube is arranged in the protecting tube, the second thermocouple wire and the first thermocouple wire are arranged in the middle of the insulating porcelain tube and at one end of the insulating porcelain tube respectively, the other end of the insulating porcelain tube is connected with the terminal block through the wiring porcelain plate, and the outgoing line hole locking nut is arranged on the outer side of the terminal block. The sheathed thermocouple for the explosion-proof transformer has the advantages of being small in diameter, bendable, resistant to high pressure and vibration, short in thermal response time, firm, durable, high in reliability and the like, and is capable of being used for measuring temperatures in two different environments at the same time, high in response speed, stable in performance and long in service life.
Description
Technical field
What the present invention relates to is a kind of temperature sensing device, is specifically related to a kind of explosion-proof transformer armoured thermocouple.
Background technology
Current explosion-proof transformer is on the market a lot of by armoured thermocouple kind, a kind of thermopair can only be measured the temperature under a kind of environment, just need to measure by two thermopairs once two kinds of close measurements are alleviated, but sometimes install in this case very inconvenient.
Summary of the invention
For the deficiency existing in prior art, the invention provides a kind of explosion-proof transformer armoured thermocouple, have that diameter is little, flexible, high pressure resistant, anti-vibration, the fast and sturdy and durable high reliability of thermal response time, it can measure two kinds of temperature under different alleviation simultaneously, reaction velocity is fast, stable performance, long service life.
To achieve these goals, the present invention realizes by the following technical solutions: a kind of explosion-proof transformer armoured thermocouple, comprise wire hole set nut, connection terminal, wiring porcelain plate, protection tube, porcelain tube, the first thermocouple wire and the second thermocouple wire, in protection tube, be provided with porcelain tube, porcelain tube middle part and one end are respectively arranged with the second thermocouple wire and the first thermocouple wire, the porcelain tube other end is connected with connection terminal by wiring porcelain plate, connection terminal arranged outside has wire hole set nut, on described wire hole set nut, be provided with two line hole stationary installations, be used for fixing two bursts of different measuring circuit.
According to above-mentioned a kind of explosion-proof transformer armoured thermocouple, wherein, described connection terminal is two.
According to above-mentioned a kind of explosion-proof transformer armoured thermocouple, wherein, on described protection tube, being provided with can erection bolt.
The present invention has that diameter is little, flexible, high pressure resistant, anti-vibration, the fast and sturdy and durable high reliability of thermal response time, it can measure two kinds of temperature under different alleviation simultaneously, reaction velocity is fast, stable performance, long service life, this thermopair is applicable to the measurement of hardware surface and internal temperature, installs simple and convenient.
Brief description of the drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention.
embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of explosion-proof transformer armoured thermocouple, comprise wire hole set nut 1, connection terminal 2, wiring porcelain plate 3, protection tube 4, porcelain tube 5, the first thermocouple wire 6 and the second thermocouple wire 7, in protection tube 4, be provided with porcelain tube 5, porcelain tube 5 middle parts and one end are respectively arranged with the second thermocouple wire 7 and the first thermocouple wire 6, porcelain tube 5 other ends are connected with connection terminal 2 by wiring porcelain plate 3, connection terminal 2 arranged outside have wire hole set nut 1, on described wire hole set nut 1, be provided with two line hole stationary installations, be used for fixing two bursts of different measuring circuit.
It should be noted that described connection terminal 2 is two.
In addition on described protection tube 4, being provided with, can erection bolt.
The temperature range that this embodiment is applicable according to compensating wire, is mainly used two kinds of compensating wires: PVC compensating wire and wire netting compensating wire, and wherein PVC compensating wire core is multiply type, quality softness is limited to 80 DEG C in heatproof; Wire netting compensating wire core is sub-thread type, and interference free performance is better, is limited to 400 DEG C in heatproof.This embodiment has that diameter is little, flexible, high pressure resistant, anti-vibration, the fast and sturdy and durable high reliability of thermal response time, and it can measure two kinds of temperature under different alleviation simultaneously, and reaction velocity is fast, stable performance, long service life.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
