DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1-2 , this embodiment provides a micro electrical sensor insulation effectiveness detector.

[0035] The micro-electrical sensor insulation effectiveness detector comprises a detection mechanism 100 .

[0036] Specifically, the detection mechanism 100 includes a base 101, and a first support frame 102 and a second support frame 107 are fixedly arranged on both sides of the surface of the base 101, and a connecting shaft 103 is also passed through the top of the first support frame 102, and a mixing barrel 104 for detecting the sensor is coaxially installed on the outside of the connecting shaft 103, and circular slide rails 105 are fixedly arranged on the periphery of both ends of the mixing barrel 104, and an auxiliary part 106 is also installed on the outer edge of the middle part of the surface of the base 101, and a connecting groove 108 is also reserved in the inner wall of the mixing barrel 104, and the connecting groove 108 is connected to an external steam generating device. When the sensor is detecting, water vapor can enter the mixing barrel 104 through the connecting groove 108 to realize the detection of the sensor.

[0037] Furthermore, the auxiliary component 106 includes a fixing frame 106a symmetrically fixed to the surface of the substrate, a rotatable shaft 106b is arranged between the two fixing frames 106a, and two auxiliary wheels 106c are symmetrically arranged on the shaft 106b, and the outer edges of the two auxiliary wheels 106c are respectively embedded in the slide rails 105 at both ends of the mixing barrel 104, so that the two auxiliary wheels 106c can assist and support the rotation of the mixing barrel 104, thereby ensuring the stability of the mixing barrel 104 during rotation.

[0038] During the test, the sensor to be tested is placed inside the mixing barrel 104, and water vapor is introduced into it through the connecting groove 108. By allowing the water vapor to contact the sensor, the insulation of the sensor is tested. At the same time, the rotatable setting of the mixing barrel 104 can ensure that the sensor is in contact with the water vapor more evenly, so as to improve the test effect.

[0039] Example 2

[0040] Reference Figure 1-6 This embodiment provides a micro electrical sensor insulation effectiveness detector, which is different from the previous embodiment in that:

[0041] A conversion mechanism 200 is also included.

[0042] Specifically, the conversion mechanism 200 includes a flip member 201 arranged on the outside of the mixing barrel 104, the flip member 201 is arranged on the connecting shaft 103, the outside of the flip member 201 is connected to a motor 202, the output end of the motor 202 is also connected to a transmission member 203, one side of the transmission member 203 is connected to a driving member 204, the outside of the driving member 204 is connected to a dispersion member 205, and a clamping member 206 is also arranged on the flip member 201.

[0043] Further, the flip member 201 includes a disk 201a connected to the motor 202, and a crescent block 201b is arranged on the outer edge of the surface of the disk 201a. A driving rod 201c is also arranged on the surface of the disk 201a. A ratchet 201d is arranged on the outer side of the driving rod 201c. The ratchet 201d is coaxially sleeved on the outside of the connecting shaft 103, and the ratchet 201d is rotatably arranged. A crescent groove 201e and a slide groove 201f are arranged on the outer edge of the surface of the ratchet 201d in sequence, and the crescent groove 201e and the slide groove 201f are arranged in a ring array on the outer side of the ratchet 201d. Accordingly, the driving rod 201c and the slide groove 201f, the crescent block 201d and the drive rod 201c are arranged on the outer side of the ratchet 201d. 01b and the crescent groove 201e cooperate with each other. When the disc 201a rotates under the drive of the motor 202, the disc 201a will synchronously drive the crescent block 201b to rotate. As the crescent block 201b rotates, it will fall into the crescent groove 201e of the ratchet 201d. At this time, the driving rod 201c will follow the crescent block 201b into the slide groove 201f on the ratchet 201d. When the crescent block 201b completes a circle of rotation, the driving rod 201c will also rotate a circle accordingly, thereby driving the slide rail 105 to drive the ratchet 201d to rotate. If the driving rod 201c does not enter the slide rail 105, the ratchet 201d will not rotate. Therefore, an intermittent motion is formed, which can drive the electrical sensor to rotate intermittently, which can effectively improve the efficiency of mutual transmission and facilitate the subsequent insulation detection of the electrical sensor.

[0044] The transmission member 203 includes a first sprocket 203a arranged on the output end of the motor 202, a first chain 203b is arranged outside the first sprocket 203a, a second sprocket 203c is arranged at the other end of the first chain 203b, a transmission shaft 203d passes through the interior of the second sprocket 203c, a third sprocket 203e is arranged on the other end of the transmission shaft 203d, a second chain 203f is arranged outside the third sprocket 203e, and a fourth sprocket 203g is arranged at the other end of the second chain 203f. When the motor 202 drives the disc 201a to rotate, it can synchronously drive the first sprocket 203a which is also located on its output shaft to rotate. Therefore, under the transmission of the second sprocket 203c, the transmission shaft 203d, the third sprocket 203e and the second chain 203f, the fourth sprocket 203g can be synchronously driven to rotate, thereby realizing the synchronous driving of the flip member 201 and the driving member 204.

[0045] The driving member 204 includes a first gear 204a arranged on the fourth sprocket 203g. The first gear 204a and the fourth sprocket 203g are coaxially arranged and can rotate synchronously. At the same time, a plurality of second gears 204b are distributed in a circular array on the periphery of the first gear 204a. The second gear 204b is meshed with the first gear 204a. Therefore, when the first gear 204a rotates with the fourth sprocket 203g, the plurality of second gears 204b can be driven to rotate synchronously. A connecting pipe 204c is also provided at the center of each second gear 204b. The connecting pipe 204c is hollow and connected to the connecting groove 108. Therefore, water vapor can enter the mixing barrel 104 through the connecting groove 108 and the connecting pipe and be dispersed under the action of the dispersing member 205.

[0046] The dispersion member 205 includes a mounting sleeve 205a disposed at the end of the connecting tube 204c, and a plurality of stirring plates 205b are disposed on the outside of the mounting sleeve 205a in a circular array. The stirring plates 205b can rotate synchronously with the rotation of the second gear 204b, so that the stirring plates 205b can stir the water vapor and guide the water vapor to be diverted. Part of the water vapor is pushed to the surface of the electrical sensor, and the other part of the water vapor enters the mixing barrel 104. The water vapor will eventually enter the mixing barrel 104 together, so that the electrical sensor is immersed in the water vapor, thereby ensuring sufficient contact between the sensor and the water vapor.

[0047] The clamping member 206 includes a fixing rod 206a arranged on the ratchet 201d, thereby realizing synchronous rotation of the clamping member 206 and the ratchet 201d, and the fixing rod 206a runs through the mixing barrel 104, thereby when the clamping member 206 rotates with the ratchet 201d, the mixing barrel 104 can be driven to rotate at the same time, and the end cover of the mixing barrel 104 and the driving member 204 that fits the mixing barrel 104 are arranged to rotate relative to each other, thereby ensuring the sealing of the mixing barrel 104 while not affecting the normal rotation of the mixing barrel 104, and a clamping sleeve 206b is arranged at the end of the fixing rod 206a, and the clamping sleeve 206b is used to place a sensor to ensure the stability of the sensor during the detection process.

[0048] When testing the insulation performance of the electrical sensor, first, the sensor is placed in the clamping sleeve 206b through the external opening of the mixing barrel 104. Then, the motor 202 drives the flip member 201 to operate, so that the ratchet 201d drives the clamping member 206 to rotate, realizing the transformation of the internal position sensors. At the same time, water vapor is introduced into the mixing barrel 104 through the connecting groove 108 and the connecting pipe to test the insulation performance of the sensor.

[0049] The detection process is divided into two states:

[0050] 1) When the second chain 203f is not installed outside the third sprocket 203e and the fourth sprocket 203g, the transmission member 203 is in a non-transmission state, that is, the motor 202 can drive the mixing barrel 104 and the flip member 201 to rotate. At this time, the water vapor introduced into the mixing barrel 104 may be layered inside the mixing barrel 104 under the action of its own density and gravity, that is, the water vapor content inside the mixing barrel 104 is different from top to bottom, and there are two or more water vapor distribution intervals inside the mixing barrel 104. Therefore, when the flip member 201 drives the clamping member 206 to rotate intermittently and the sensor position is changed, the insulation performance of the sensor under different water vapor contents at the same time can be detected according to the different positions of different sensors, and the insulation performance of the sensor under different humidity and different time can be detected by adjusting the intermittent rotation frequency of the flip member 201;

[0051] 2) When the second chain 203f is installed outside the third sprocket 203e and the fourth sprocket 203g, the transmission member 203 is in a transmission state, that is, the motor 202 drives the mixing barrel 104, the flip member 201 and the dispersion member 205 to rotate through the transmission member 203. At this time, the water vapor introduced into the mixing barrel 104 is evenly distributed to various parts of the mixing barrel 104 under the diversion of the dispersion member 205. The water vapor content in various parts of the mixing barrel 104 is consistent, that is, the sensors at various positions can fully contact with the water vapor, thereby allowing multiple sensors to perform synchronous detection at the same humidity.

[0052] In summary, through the setting of the flip part 201, the insulation performance of the sensor can be detected under different humidity conditions. At the same time, with the linkage cooperation between the transmission part 203, the driving part 204 and the dispersion part 205, the synchronous detection of multiple groups of sensors under the same humidity conditions can also be realized, and the sensors can be fully in contact with water vapor. While improving the detection efficiency of the detector for the insulation performance of the sensor, the detection capability of the detector can be enhanced to ensure the accuracy of the detection results, which is convenient for simultaneously detecting the insulation performance of the sensor under different humidity, reducing the use limitations of the detector, and can quickly obtain the humidity range of the sensor under safe working conditions. While ensuring the detection accuracy of the detector, it meets the user's needs for detecting the insulation performance of the sensor under different humidity.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
