The utility model discloses a metal conduit fixes the temperature probe, guarantees that the thermistor of tip suspends in transformer oil, through embedded detection loop, whether locating place that can the automated inspection temperature probe is reasonable, has guaranteed the measurement accuracy of transformer top layer oil temperature, and this device convenient to use can effectively improve test efficiency.
Description
Technical field
The utility model belongs to substation transformer experimental technique field, the stationary installation of temperature probe in especially a kind of oil immersion-type distribution transformer temperature rise test.
Background technology
Transformer temperature rise test is for verifying whether the medial temperature of winding exceedes temperature limit under oepration at full load condition.In transformer temperature rise test, top-oil temperature is important detection data, and its accuracy can affect the judgement of test findings.Substation transformer top of oil-tank is provided with the base for temperature probe.During temperature rise test, temp probe is put into the top-oil temperature that base gets final product measuring transformer.Temp probe generally adopts thermistor, pops one's head in be connected by plain conductor with between temperature measurer.Temp probe is put into base, and the thermistor of end is difficult to be suspended in the transformer oil in base, and the bending stress of plain conductor can make probe be attached on base inwall.Because base inwall contacts with extraneous air, there is certain temperature difference with inner oil temperature, therefore can cause measuring error when probe is attached to base inwall, affect the accuracy of temperature rise test.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of reasonable in design, stationary installation of measuring temperature probe in oil immersion-type distribution transformer temperature rise test accurate, easy to use.
The utility model solves its technical matters and takes following technical scheme to realize:
The stationary installation of temperature probe in a kind of oil immersion-type distribution transformer temperature rise test, comprise conduit, geometrical clamp, connecting rod and base, described conduit is that a hollow metal pipe is for installing the plain conductor of temperature probe, described geometrical clamp is metal holder and is clamped on conduit, described connecting rod is that Metallic rod is for connection fixing clamp and base, a pilot lamp is provided with at the top panel of base, the bottom of base is sheet metal, at bottom setting-in one block permanent magnet of base, a battery folder is provided with in the bottom of base, in battery folder inside, the measure loop that battery is chassis interior is housed and direct supply is provided, this measure loop by pilot lamp and direct supply in series, measure loop one end is connected with metal link rod, the measure loop other end is connected with the metal base plate of base.
And the mounting means of described connecting rod and geometrical clamp, base is: one end of connecting link is packed in the side of geometrical clamp, and the other end of connecting link is downward-sloping to be packed on the top panel of base.
And the top panel of described base is made up of plastic material.
And the internal diameter of described conduit is slightly larger than the plain conductor of temperature probe.
Advantage of the present utility model and good effect are:
The utility model fixes temperature probe by a metal catheter, ensures that the thermistor of end is suspended in transformer oil; Meanwhile, the embedded measure loop of this device, whether the putting position that automatically can detect temperature probe is reasonable, and ensure that the measurement accuracy of transformer top-oil temperature, this device is easy to use, effectively can improve test efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the upward view of Fig. 1;
Fig. 4 is the measure loop circuit diagram of chassis interior.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
A stationary installation for temperature probe in oil immersion-type distribution transformer temperature rise test, as shown in Figure 1 to Figure 3, comprises conduit 1, geometrical clamp 2, connecting rod 3 and base 4.Described conduit is a hollow metal pipe, and internal diameter is slightly larger than the plain conductor of temperature probe; Described geometrical clamp is a metal holder, in order to A/C position in the axial direction; Described connecting rod is a Metallic rod, in order to connection fixing clamp and base, one end of connecting rod is packed in geometrical clamp side, the other end of connecting rod is downward-sloping to be packed on the top panel of base, the top panel of described base is adopted made of plastic, a pilot lamp 5 is provided with, in order to indicate the position of conduit whether reasonable at the top panel of base.The bottom of base is sheet metal, inlays a block permanent magnet 6, can be adsorbed on transformer case in the bottom of base, in order to firm banking, be provided with a battery folder 7 at base bottom, in battery folder inside, battery be housed, for the measure loop of chassis interior provides direct supply.The measure loop of chassis interior, as shown in Figure 4, this measure loop by pilot lamp and direct supply in series.One end, loop a is connected with metal link rod, and loop other end b is connected with the metal base plate of base.
Place temperature probe time, will pop one's head in plain conductor pass conduit, the base of stationary installation is fixed on transformer case.Unclamp geometrical clamp, make conduit stretch in the base of transformer top, be fixedly clamped after adjusting upper-lower position folder.If the tube wall of conduit touches on base inwall, then likely make the thermistor of probe end touch base inwall, now the bottom of conduit, geometrical clamp, connecting rod, measure loop ab, base and transformer case define galvanic circle, and pilot lamp is luminous.Adjustment position base, illustrates that when pilot lamp is not luminous temperature probe putting position is reasonable, can not touch base inwall.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
