Abstract
The utility model discloses a transformer temperature control device and solves the problems that the upper space and the lower space of the existing transformer thermometer are very small, the butt-connection is difficult, effort-consuming and time-consuming and the like. The transformer temperature control device is characterized in that a junction box (3) and a multi-strand flexible copper cable connecting wire (4) are added between a thermometer (1) and a secondary cable (2), the hard core wires of the secondary cable (2) are respectively connected with a terminal (5) in the junction box, the thermometer (1) is connected with the terminal (5) in the junction box through the connecting wire (4), one end of a temperature control line (6) is connected with the thermometer (1) and the other end of the temperature control line (6) is fixedly connected onto the shell of the transformer. The transformer temperature control device has the advantages of low mounting and dismounting labor intensity, high working efficiency and the like, and can be widely used for transformers in all kinds of substations.
Description
One, technical field
The utility model belongs to transformer station for transformation facility, relates in particular to a kind of transformer attemperating unit of transformer station.
Two, background technology
At present; the transformer of each transformer station often adopts thermometer to be compound temperature sensor on the market; mainly form by flexible member, kapillary and thermometer bulb; in the closed system that these three parts are formed, fill temperature sensing liquid; when temperature variation; the volume of the temperature sensing liquid in the thermometer bulb is linear change thereupon also; be passed to the flexible member in the table and produce certain displacement by kapillary; after amplifying, mechanism points out temperature scale; and when uniform temperature, trigger microswitch, control transformer cooling system and protection loop.Temperature distant place numeral shows then by pt100 thermal resistance output signal, cooperates XMT series distant place digital indicator to finish.All thermometer electric contacts and thermal resistance electric signal pick out from thermometer to the main-transformer terminal box by secondary cable, constitute the loop and finish every function.Must change verification because thermometer is annual, and thermometer watchcase internal wiring narrow space, terminal are little, used secondary cable is hard heart yearn, Yun Hang cable pierces into and extracts fragile insulation course out for many years, the aging cable grounding of broken skin may cause short circuit, exists and changes trouble, time and effort consuming and potential safety hazard.
Three, summary of the invention
The purpose of this utility model is can change easy, safe and reliable transformer attemperating unit for market provides a kind of.
The technical solution of the utility model is: it is made of thermometer, secondary cable and temperature control line etc., between thermometer and secondary cable, set up a terminal box, big connection terminal is set in terminal box, and be fixed on the installation base plate of thermometer, the hard heart yearn of secondary cable is linked to each other with the connection terminal of a side in the terminal box respectively, the opposite side connection terminal is connected with thermometer wiring small terminal by the connecting line of setting up, and described connecting line is a multiply soft copper cable.One end of temperature control line connects thermometer, and the other end is fixedly connected on the transformer case.
The beneficial effects of the utility model are: owing to set up terminal box between secondary cable and thermometer, thereby avoided hard heart yearn to be connected with the direct of little connection terminal in the thermometer, the increase of wiring space and connection terminal, the replacing process is very easy, eliminates the potential safety hazard that the cable damage in insulation causes.
The utility model is described in further detail below in conjunction with accompanying drawing:
Four, description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 is thermometer, and 2 is secondary cable, and 3 are the temperature control line, and 4 is connecting line, and 5 is big connection terminal, and 6 are the temperature control line.
Five, embodiment
As shown in Figure 1, on the base plate that thermometer 1 is installed, set up a terminal box 3, the interior little connection terminal of big connection terminal 5 in the described terminal box 3 and thermometer 1 is corresponding, and one side terminal 5 links to each other with the connecting line of setting up 4, and this connecting line 4 is a multiply soft copper cable.5 of opposite side connection terminals in the terminal box 3 are continuous with the two alternating current cables 2 that are connected the transformer terminal case.When implementing the utility model, when needs were changed thermometer, splicing ear 5 was turned in the terminal box 3 that only needs to link to each other with connecting line 4, connecting line 4 and thermometer 1 together can be taken off and send relevant department's check, changed the good thermometer of verification 1 simultaneously.Owing to upper and lowerly all between soft copper cable and big connection terminal, carry out, operate very easyly, to have avoided in the connection of narrow space inside conductor, work efficiency is greatly improved, and can be widely used on the transformer of all kinds of transformer stations.
Claims (2)
1. transformer attemperating unit, it comprises thermometer (1), secondary cable (2) temperature control line (6), it is characterized in that: between thermometer (1) and secondary cable (2), set up a terminal box (3), big connection terminal (5) is set in terminal box (3), and be fixed on the installation base plate of thermometer (1), the hard heart yearn of secondary cable (2) is linked to each other with the connection terminal (5) of a side in the terminal box (3) respectively, opposite side connection terminal (5) is connected with thermometer wiring small terminal by the connecting line of setting up (4), one end of temperature control line (6) connects thermometer (1), and the other end is fixedly connected on the transformer case.
