Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, and in particular to a passive node verification indicator device and system. Background Technology

[0002] The main transformer temperature monitoring device often uses a pressure thermometer. Pressure thermometers require periodic step tests of temperature readings and operating points using a dry-type furnace as a stable heat source. On-site node verification typically uses a multimeter to test continuity to determine the node's operating value and return value. During actual verification, staff usually need to simultaneously test the node continuity with a multimeter and observe the meter readings to determine the operating and return values. Since the dry-type furnace takes a relatively long time to reach a stable temperature (around 10 minutes), staff often connect the multimeter pointer to the node for easy observation of continuity. However, pressure thermometers typically have multiple pairs of external nodes for starting the cooler or as alarm trip signals. This necessitates frequent disconnection and reconnection of the multimeter between multiple pairs of nodes, or connecting multiple multimeters simultaneously. This method is not only labor-intensive and resource-intensive but also prone to inaccurate results, affecting work efficiency and accuracy. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Reference Figures 1-4 This embodiment provides a passive node verification indicator device, including a power supply 1 and an indicator component 2.

[0028] Specifically, the passive node calibration indicator device includes at least two parallel indicator components 2; each indicator component 2 includes a reset button 21, an indicator light 22, and a pin 23 connected in series; a power supply 1, connected in series with the indicator components 2, supplies power to the indicator components 2. Four indicator components 2 are provided, connected in parallel. Because the calibration time is relatively long, the reset button can save battery power. The pin 23 is connected to the lower side of the terminal block of the pressure thermometer via a wire 8. When the node branch is closed, the indicator light 22 illuminates, indicating that the node is not faulty; when the node branch is open, the indicator light 22 goes out, indicating that the node is faulty and needs repair.

[0029] Furthermore, the power supply 1 and indicator light 22 are both housed in the housing 5. A groove 51 is provided on one side of the housing 5, and the power supply 1 is housed in the groove 51. A switch 6 is also fixedly installed on one side of the power supply 1. The switch 6 is the main switch of the device. Before node verification, the switch 6 is turned off, the device is connected to the terminal block node to be tested with the wire 8, and then the switch 6 is closed. The continuity of the node can be determined by observing the lighting and extinguishing of the indicator light.

[0030] Better, such as Figure 6 As shown, a hole is provided on the side of the housing 5. In use, the wire 8 passes through the hole and connects to the socket of the pressure thermometer terminal block. One end of the wire 8 is fixedly provided with a pin 23. The pin 23 is U-shaped and fits into the socket. One end of the pin 23 is placed in the socket, and the other end is fastened to the outside of the socket 23 for fixation, making the pin 23 more stable and more convenient to use. After use, the wire 8 and the pin 23 are collected in the collection groove 52.

[0031] Ideally, indicator light 22 is an LED, and power supply 1 is a 6V battery.

[0032] Preferably, a fixing element 7, which is a magnet, is also provided on the bottom side of the housing 5. When we perform calibration, the housing 5 can be attached to the cabinet door for easy manual operation.

[0033] When using it, first attach the housing 5 to the cabinet door near the terminal block, connect the pin 23 to the node of the terminal block with the wire 8, then close the switch 6 and observe the indicator light coming on and off.

[0034] In summary, this device enables the simultaneous testing of the continuity of multiple pairs of nodes, improving work efficiency and data accuracy.

[0035] As an optional embodiment, this embodiment provides a passive node verification indicator device.

[0036] Specifically, such as Figure 5 As shown, the passive node calibration indicator device includes at least two parallel indicator components 2; the indicator component 2 includes a reset button 21, an indicator light 22 and a pin 23 connected in series; the pin 23 is used to connect to the terminal block of the pressure thermometer; the power supply 1 is connected in series with the indicator component 2 and supplies power to the indicator component 2.

[0037] Furthermore, the power supply 1 and indicator light 22 are both housed in the housing 5. A groove 51 is provided on one side of the housing 5, and the power supply 1 is housed in the groove 51. A switch 6 is also fixedly installed on one side of the power supply 1.

[0038] The bottom side of the housing 5 is also provided with a fixing component 7, which is a suction cup. The suction cup is attached to the device near the terminal block to facilitate the verification of wiring.

[0039] In summary, the installation of fastener 7 makes operation more convenient for staff, wiring faster, and improves work efficiency.

[0040] As an optional embodiment, this embodiment provides a collection slot 52 for a passive node verification indicator device.

[0041] Specifically, such as Figure 4 As shown, a collection groove 52 is also provided at the bottom of the housing 5. The collection groove 52 cooperates with the cover plate 53. A through hole 531 is provided on the side of the cover plate 53 near the pin 23. The through hole 531 corresponds one-to-one with the pin 23. The collection groove 52 is used to collect the wires 8 together to prevent the wires 8 from scattering. The wires 8 pass through the through hole 531 and are placed in the collection groove 52. Then the cover plate 53 is engaged with the inner wall of the collection groove 52.

[0042] When in use, open the cover plate 53, take out the wire 8 inside the collection tank 52, and then connect the wire 8 to the node according to the node sequence of the terminal block. Turn on the switch 6 to power on the circuit and observe the lighting and extinguishing of the indicator light 22. When the indicator light 22 of a certain branch is lit, it means that there is no fault between the nodes. When the indicator light 22 of a certain branch is extinguished, it means that there is an open circuit between the nodes and a fault has occurred, which requires maintenance.

[0043] In summary, the collection slot 52 makes it easier to store the wires 8, and the power status of the nodes can be directly determined by the indicator lights, thus improving work efficiency.
