Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment one: shown in accompanying drawing 1, a kind of insulation rod Group test device, comprises the some groups of test assemblies 1 for fixed insulation rod 3 and the corresponding temperature measuring equipment 2 detecting the temperature often organizing the insulation rod 3 in test assembly 1.If be connected to testing transformer 4 two ends with group test assembly 1, one end output voltage of testing transformer 4 and other end ground connection.Often organize test assembly 1 and can fix an insulation rod 3, thus can test many insulation rods 3 simultaneously.Shown in accompanying drawing 1, two groups of test assemblies 1 are example, in fact can arrange the group number of required test assembly 1 as required, such as 10 groups.Need that there is gap between two groups of adjacent test assemblies 1, as the gap of at least 50mm, to make the test of adjacent insulation rod 3 mutually to disturb, ensure the accuracy of test.Temperature measuring equipment 2 adopts infrared surveillance set, often can organize test assembly 1 correspondence and a temperature measuring equipment 2 is set, also a temperature measuring equipment 2 can be set a whole set of test unit, by the control to this temperature measuring equipment 2, can 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.
Often organize test assembly 1 and comprise 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 the two ends fixing an insulation rod 3, the distance between two fixed terminals 11 can regulate according to the length of insulation rod 3 to be tested.
Shown in accompanying drawing 2 and accompanying drawing 3, fixed terminal 11 comprises can opening and closing and the supporting member 112 of metal of the set collar 111 of conduction, carrying 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.When set collar 111 is opened, it forms an opening, can put into insulation rod 3 wherein by this opening or be taken out by insulation rod 3 wherein; And when set collar 111 is closed, its insulation rod 3 is bound round located therein and with the periphery close contact of insulation rod 3, thus the two ends of insulation rod 3 to be connected with the two ends of testing transformer 4 respectively, now can to test insulation rod 3 making alive.Simultaneously, set collar 111 also needs arrange a locking system 113, when set collar 111 is in closed condition, set collar 111 can be locked in closed condition by this locking system 113, and after having tested, locking system 113 can unlock and make set collar 111 open.
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 identical major arc of radian, 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 relatively rotates in vertical plane.Supporting member 112 is divided into two parts, and supports two arcuate members 114 from below respectively.One end be hinged of two arcuate members 114 is connected with an elastic component, this elastic component can vertically place generation elastic deformation, in the present embodiment, elastic component selects volute spring 115, this volute spring 115 is arranged between two parts of supporting member 112, and the larger one end of its end face 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 makes the end of another arcuate member 114 can insert wherein for hollow-core construction.The open mode of set collar 111 and the conversion of closed condition can be realized by relatively rotating of two arcuate members 114.When closing set collar 111, that not hinged one end of an arcuate member 114 can be inserted within that not hinged one end of another hollow arcuate member 114, thus the annulus that formation one is complete.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, near the position of its that not hinged end in that hollow arcuate member 114, be provided with thrust spring 116, this thrust spring 116, when another arcuate member 114 inserts the arcuate member 114 at its place, can ensure the two good contact and insertion.
In order to realize effective encirclement to the circumference of insulation rod 3, solve insulation rod 3 diameter error and guarantee set collar 111 and insulation rod 3 close contact and do not damage insulation rod 3 by pressure, flexible liner is provided with as compensation mechanism in set collar 111, flexible liner is spring liner 117, its to 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 test time, hold insulation rod 3 and it is put into set collar 111 by the opening between two arcuate members 114 and pressing downwards, insulation rod 3 touches the pin joint of two arcuate members 114 and continues pressing volute spring 115 downwards, two arcuate members 114 are made to relatively rotate and close gradually, the end of an arcuate member 114 is inserted in the end of another arcuate member 114, and two arcuate members 114 are automatically locked by locking system 113 when reaching off-position, now, set collar 111 reaches closed condition, it is located on the excircle of insulation rod 3 around hoop, thus realize the reliable fixing of insulation rod 3, as shown in Figure 3.
The two ends of every root insulation rod 3 are all fixed on two fixed terminals 11 in same group of test assembly 1 by said method, when installing whole insulation rod 3 of single test, can test, by testing transformer 4 pairs of insulation rod 3 making alives, use the epoxy resin whether abnormal heating of every root insulation rod 3 in temperature measuring equipment 2 detection experiment process.
When after off-test, unlock locking system 113, the elastic force of volute spring 115 makes two arcuate members 114 relatively rotate and return to open mode gradually, now, allows testing crew to take out the insulation rod 3 having terminated test, and is that test next time is ready.
This insulation rod Group test device, monitors the abnormal heating of epoxy resin on the one hand, avoids the mode that after having a power failure, testing crew touches with hand in process of the test with infrared facility, safe and reliable; There is the space of 50mm between rod rod, avoid heat conducting erroneous judgement occurs; In addition, complete equipment single test 10 insulation rods 3, guarantee to carry out Validity Test to each root rod while improving test efficiency.This insulation rod Group test device, the specification experiment process of insulation rod 3, improves test efficiency, makes whole process of the test safe and reliable, make a line production safety situation reliably controlled.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
