Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
Embodiment mono-: shown in accompanying drawing 1, a kind of insulation rod Group test device, comprises the some groups of temperature measuring equipments 2 for the test assembly 1 of fixed insulation rod 3 and the temperature of the corresponding insulation rod 3 that detects every group of test assembly 1.If be connected to testing transformer 4 two ends, one end output voltage of testing transformer 4 and other end ground connection with group test assembly 1.Every group of test assembly 1 can be fixed an insulation rod 3, thereby can test many insulation rods 3 simultaneously.Shown in accompanying drawing 1, two groups of test assemblies 1 are example, and in fact the group number of required test assembly 1 can be set as required, for example 10 groups.Between two groups of adjacent test assemblies 1, need to there is gap, as the gap of 50mm at least, can phase mutual interference with the test that makes adjacent insulation rod 3, ensure the accuracy of test.Temperature measuring equipment 2 adopts infrared surveillance set, can a temperature measuring equipment 2 be set every group of test assembly 1 correspondence, also can a temperature measuring equipment 2 be set a whole set of test unit, by the control to this temperature measuring equipment 2, can be to insulation rod 3 probe temperature successively in each group of test assembly 1.Infrared surveillance set utilizes infrared ray to measure the temperature of insulation rod 3, and it is non-contact temperature measuring device 2, and has degree of precision.
Every group of test assembly 1 comprises two fixed terminals 11, these two fixed terminals 11 are connected with the two ends of testing transformer 4 respectively, and two fixed terminals 11 are respectively used to fix the two ends of an insulation rod 3, the distance between two fixed terminals 11 can regulate according to the length of insulation rod to be tested 3.
Shown in accompanying drawing 2 and accompanying drawing 3, fixed terminal 11 comprises the set collar 111 that can open and close and conduct electricity, the supporting member 112 that carries the metal of set collar 111.Set collar 111 is connected with testing transformer 4, and it is for the end of fixed insulation rod 3.This set collar 111 has open mode and closed condition.In the time that set collar 111 is opened, it forms an opening, can be put into wherein insulation rod 3 or insulation rod wherein 3 is taken out by this opening; And in the time that set collar 111 is closed, its by insulation rod 3 bind round located therein and with the periphery close contact of insulation rod 3, thereby the two ends of insulation rod 3 are connected with the two ends of testing transformer 4 respectively, now can test insulation rod 3 making alives.Simultaneously, on set collar 111, also need to arrange a locking system 113, when set collar 111 is during in closed condition, this locking system 113 can be locked in closed condition by set collar 111, and after having tested, locking system 113 can releases and set collar 111 is opened.
Set collar 111 comprises two arcuate members 114, and this arcuate member 114 is at least semi arch, in the present embodiment, adopts the arcuate member 114 of the major arc that radian is identical, and it can form a complete annulus and match with the excircle of insulating bar.One end of two arcuate members 114 is hinged and can in vertical plane, relatively rotates.Supporting member 112 is divided into two parts, and respectively from two arcuate members 114 of below supporting.One end being hinged of two arcuate members 114 is connected with an elastic component, this elastic component can vertically placed generation elastic deformation, in the present embodiment, elastic component is selected volute spring 115, this volute spring 115 is arranged between two parts of supporting member 112, and one end that its end face is larger is connected with supporting member 112, and the less one end of end face is connected to the hinged place of arcuate member 114.One of them root arcuate member 114 can insert wherein for hollow-core construction makes the end of another arcuate member 114.Can realize the conversion of open mode and the closed condition of set collar 111 by relatively rotating of two arcuate members 114.In the time closing set collar 111, within that not hinged one end of another hollow arcuate member 114 can be inserted in that not hinged one end of an arcuate member 114, thereby form a complete annulus.Owing to adopting the arcuate member 114 of major arc, so two arcuate members 114 of the set collar 111 after closing have one section of lap, in this section of lap, locking system 113 can be set, in the present embodiment, this locking system 113 is arranged at the middle part of lap.Locking system 113 can design as required, as long as can realize locking and unlocking function, is not limited to certain form.In addition, in that hollow arcuate member 114, near the position of its that not hinged end, be provided with thrust spring 116, this thrust spring 116, in the time that another arcuate member 114 inserts the arcuate member 114 at its place, can ensure the two good contact and insertion.
Realize effectively for the circumference to insulation rod 3 and surround, solve insulation rod 3 diameter error and ensure set collar 111 with insulation rod 3 close contacts and do not damage insulation rod 3 by pressure, in set collar 111, be provided with flexible liner mechanism by way of compensation, flexible liner is spring liner 117, its be arranged between set collar 111 and insulation rod 3 and with the two good contact.
The use procedure of this fixed terminal 11 is as follows: the original state of set collar 111 is open mode, as shown in Figure 2.When needs carry out insulation rod 3 while testing, hold insulation rod 3 and it is put into set collar 111 and pressed downwards by the opening between two arcuate members 114, insulation rod 3 touches the pin joint of two arcuate members 114 and continues to press volute spring 115 downwards, make two arcuate members 114 relatively rotate and close gradually, insert in the end of another arcuate member 114 end of an arcuate member 114, and by locking system 113, two arcuate members 114 are automatically locked in the time reaching off-position, now, set collar 111 reaches closed condition, it is located at around hoop on the excircle of insulation rod 3, thereby realize the reliable fixing of insulation rod 3, as shown in Figure 3.
The two ends of every insulation rod 3 are all fixed on two fixed terminals 11 in same group of test assembly 1 by said method, in the time installing whole insulation rod 3 of single test, can test, to insulation rod 3 making alives, use temperature measuring equipment 2 to detect the whether abnormal heating of epoxy resin of every insulation rod 3 in process of the test by testing transformer 4.
When after off-test, release locking system 113, the elastic force of volute spring 115 makes two arcuate members 114 relatively rotate and return to gradually open mode, now, allows testing crew to take out the insulation rod 3 that has finished test, and is that test next time is ready.
This insulation rod Group test device, one side monitors the abnormal heating of epoxy resin in process of the test with infrared facility, avoid the mode that after having a power failure, testing crew touches with hand, safe and reliable; Between rod rod, there is the space of 50mm, avoid occurring heat conducting erroneous judgement; In addition, 10 insulation rods 3 of complete equipment single test, when improving test efficiency guarantee each root rod to carry out Validity Test.This insulation rod Group test device, specification the experiment process of insulation rod 3, improved test efficiency, make whole process of the test safe and reliable, make a line production safety situation controlled reliable.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
