Description

Technical Field

[0002] As an important accessory of a transformer, the temperature measurement device is mainly used to monitor the internal oil temperature and winding temperature of the transformer, and is one of the most intuitive means to judge the operation condition of the transformer. At present, pressure thermometers are usually used for temperature monitoring of transformers. However, due to design limitations, when a mechanical component or board of the pressure thermometer fails, the entire thermometer often needs to be replaced, rather than just the faulty component, resulting in high costs and long time consumption; during replacement, power outage of the transformer must be carried out, which also reduces the power supply reliability. In addition, each replacement requires the operator to work at height to install the temperature measurement device into the temperature measurement port at the top of the transformer, posing a high safety risk; at the same time, due to differences in manufacturers and models of transformers, the positions of the temperature measurement ports are different, making the installation operation of the temperature measurement device difficult. Summary of the Invention

[0003] The purpose of the present invention is to provide a tooling for a transformer temperature measurement device and a quick-insert type temperature measurement device, to solve the above technical problems, improve the versatility and adaptability of the device, avoid frequent working at height by operators, reduce the complexity of installation, and improve work efficiency and safety.

[0004] The present invention is realized through the following technical solutions: A tooling for a transformer temperature measurement device, used to install the temperature measurement device into the temperature measurement port of the transformer. A sliding component is horizontally and transversely connected to the transformer.

The transmission component includes a driving wheel and a driven wheel driven by a chain. A sliding groove for adjusting the position of the driven wheel to change the horizontal longitudinal movement distance of the temperature measurement device is formed on the sliding component.

[0005] Further, the transmission component includes a vertical section, a turning section, and a docking section. The vertical section extends towards the ground. The turning section changes the chain transmission direction through a turning wheel and a driven wheel. The outer edge of the docking section is vertically positioned and aligned with the temperature measurement port.

[0006] Further, a horizontal slide rail is arranged on the transformer. The sliding component includes clamping plates arranged on both sides of the driving wheel and the driven wheel and a connecting rod between the clamping plates.

[0007] Further, the temperature measurement device is detachably connected to the chain through a hoop.

[0008] Further, a plurality of adjusting teeth that are in interference fit with the rotating shaft of the driven wheel are uniformly arranged on the inner wall of the sliding groove.

[0009] A quick-insert type temperature measuring device includes a sensor unit, a signal conversion unit, and a communication display unit. The sensor unit is inserted into a temperature measuring port for monitoring the temperature change inside the transformer. The sensor unit is connected to the signal conversion unit through an aviation plug, and the signal conversion unit is signal-connected to the communication display unit.

[0010] Further, a guiding tapered opening is provided at the top of the temperature measuring port, and a sealing plug that cooperates with the guiding tapered opening is sleeved on the sensor unit.

Detailed implementation manners

[0021] The following is the detailed implementation manner in combination with the attached drawings.

[0022] Embodiment

[0023] As Figures 1-3 shown, in this embodiment, a tooling for a transformer temperature measuring device is mainly disclosed, which is used to install the temperature measuring device 1 into the temperature measuring port 20 of the transformer 2. A sliding assembly 3 is horizontally and transversely connected to the transformer 2. A transmission assembly 4 for transferring and inserting the temperature measuring device 1 into the temperature measuring port 20 is arranged in the sliding assembly 3. The transmission assembly 4 includes a driving wheel 41 and a driven wheel 42 driven by a chain 40. A sliding groove 30 for adjusting the position of the driven wheel 42 to change the horizontal longitudinal movement distance of the temperature measuring device 1 is formed on the sliding assembly 3. Specifically, for the position differences of the temperature measuring ports 20 on transformers 2 of different manufacturers and different models, the entire sliding assembly 3 can be horizontally and transversely moved, and the relative position of the driven wheel 42 can be adjusted to meet the installation of the temperature measuring device 1 for temperature measuring ports 20 at different positions, improving the versatility and adaptability of the device. After adjusting the tooling to align with the temperature measuring port 20, the temperature measuring device 1 is inverted and fixed on the chain 40, and is fixed outside the chain 40 to prevent jamming and ensure smooth transfer. Then, the driving wheel 41 is rotated by hand or by a motor to lift the temperature measuring device 1 until the temperature measuring device 1 is inserted into the temperature measuring port 20 and the driving wheel 41 can no longer rotate, that is, the installation of the temperature measuring device 1 is realized. It should be noted that when the temperature measuring device 1 is installed in place, the driving wheel 41 is locked and fixed, so that the transmission assembly 4 is relatively fixed, ensuring that the temperature measuring device 1 always keeps in close contact with the temperature measuring port 20. When the temperature measuring device 1 fails or needs to be repaired, only the locking of the driving wheel 41 needs to be released, and the driving wheel 41 is reversed, then the temperature measuring device 1 can be pulled out and retracted to the lower part, effectively avoiding the frequent climbing operation of the operator, reducing the complexity of installation, and improving the work efficiency and safety.

[0024] Furthermore, in a specific implementation, the transmission assembly 4 provided in the embodiment of the present invention includes a vertical section 401, a turning section 402 and a docking section 403. The vertical section 401 extends toward the ground, the turning section 402 changes the transmission direction of the chain 40 through the steering wheel 43 and the driven wheel 42, and the outer edge of the docking section 403 is vertically positioned to align with the temperature measuring port 20, so that the temperature measuring device 1 can be effectively positioned and docked to the temperature measuring port 20, thereby improving the overall working convenience and accuracy.

[0025] Furthermore, in a specific implementation, a horizontal slide rail 5 is provided on the above-mentioned transformer 2 provided in an embodiment of the present invention, and the sliding assembly 3 includes a clamping plate 31 arranged on both sides of the driving wheel 41 and the driven wheel 42 and a connecting rod 32 between the clamping plates 31, and the connecting rod 32 is provided with a sliding rod 33 that slides with the horizontal slide rail 5; specifically, the driving wheel 41, the driven wheel 42 and the steering wheel 43 can all be rotatably installed between the clamping plate 31 to provide support for the transmission assembly 4; it is only necessary to install the horizontal slide rail 5 on the existing transformer 2, and the connection of the tooling is achieved through the cooperation between the horizontal slide rail 5 and the sliding rod 33.

[0026] Furthermore, in a specific implementation, the temperature measuring device 1 provided in the embodiment of the present invention is detachably connected to the chain 40 via a clamp; this allows the temperature measuring device 1 to be quickly disassembled and installed when replacement or maintenance is required, thereby avoiding a complicated disassembly process, shortening maintenance time, and improving work efficiency.

[0027] Furthermore, in a specific implementation, the inner wall of the above-mentioned slide groove 30 provided in the embodiment of the present invention is evenly provided with a plurality of adjustment teeth 301 that are interference fit with the rotating shaft of the driven wheel 42; specifically, the slide groove 30 is opened on the clamping plate 31. When the position of the driven wheel 42 needs to be adjusted, it is only necessary to force the driven wheel 42 to cross the adjustment teeth 301, thereby changing the relative position of the driven wheel 42 in the slide groove 30, and coordinating with the adjustment of the remaining driven wheels 42 to ensure that the chain 40 always remains in a tensioned state.

[0028] like Figure 4As shown, in this embodiment, a quick-insert temperature measuring device is also disclosed, which includes a sensor unit 6, a signal conversion unit 7, and a communication display unit 8. The sensor unit 6 is inserted into the temperature measuring port 20 to monitor the temperature change in the transformer 2. The sensor unit 6 is connected to the signal conversion unit 7 through an aviation plug, and the signal conversion unit 7 is signal-connected to the communication display unit 8. Specifically, the sensor unit 6 can be a platinum resistance temperature sensing element wrapped by a protective sleeve, which converts the temperature change into a resistance change and transmits it to the signal conversion unit 7. The signal conversion unit 7 transmits the temperature to the communication display unit 8 as an electrical signal by measuring its resistance. It should be noted that the communication display unit 8 can be set at a convenient position under the transformer 2 through a connecting wire. When installing the temperature measuring device 1, the installation status can also be judged by observing the temperature value of the communication display unit 8. Through this quick-insert split design, the temperature measuring device 1 can realize the separate replacement of different faulty components, saving costs.

[0029] Furthermore, in specific implementation, a guiding conical port 200 is provided at the top of the above-mentioned temperature measuring port 20 provided in the embodiment of the present invention, and a sealing plug 61 that cooperates with the guiding conical port 200 is sleeved on the sensor unit 6. The guiding conical port 200 is in a conical shape with a larger upper part and a smaller lower part, which helps to guide the sensor unit 6 to accurately enter the temperature measuring port 20 and reduces the installation accuracy of the temperature measuring device 1 to a certain extent. At the same time, combined with the design of the sealing plug 61, good sealing performance is ensured, the influence of the external environment on the measurement accuracy is reduced, and more accurate temperature data is obtained. Preferably, a magnetic suction cup 62 magnetically connected to the temperature measuring port 20 is provided on the sealing plug 61, which enhances the stability of the device and reduces the influence of the manual operation process on the position of the sensor.

[0030] Furthermore, in specific implementation, a sealing ring 21 is provided around the temperature measuring port 20 of the above-mentioned transformer 2 provided in the embodiment of the present invention, and a protective cover 63 that cooperates with the sealing ring 21 is sleeved on the sensor unit 6. It effectively prevents the intrusion of dirt and liquid and extends the service life of the device.
