[0002] In power systems, electronic sensors used in pole-mounted circuit breakers are key monitoring components. Their performance and accuracy are crucial to ensuring stable grid operation. Therefore, rigorous testing of these sensors is an essential component of the production process. However, existing testing methods primarily rely on external mounting on the circuit breaker itself, which has exposed numerous limitations and issues in practice.

[0003] Specifically, the existing testing method has the following major drawbacks: First, since the circuit breaker body weighs more than 90 kilograms, the lifting and moving process is laborious, which is time-consuming and labor-intensive when testing electronic sensors; second, the installation process is complicated, which is not only time-consuming but also cumbersome to operate, affecting the efficiency of the test; third, due to design limitations, only one sensor can be tested at a time, which reduces the efficiency of the test; in addition, the existing testing method also has safety hazards, such as test anomalies and risks that may be caused by poor contact, and insufficient insulation to the ground.

[0027] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0030] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 4 As shown, a pole-mounted circuit breaker electronic sensor test fixture includes: a main frame 1, which provides structural support; a plurality of hanging components, each of which includes a conductive rod 2 and a bottom bracket 3; one end of the conductive rod 2 is fixedly connected to the main frame 1, and the other end is horizontally suspended and connected to the terminal 4; the bottom bracket 3 is arranged below the conductive rod 2 and fixed to the main frame 1; the conductive rod 2 is used to pass through the upper part of the sensor to be tested to mount it; the bottom bracket 3 is used to support the bottom of the sensor to be tested.

[0032] Among them, the main bracket 1 is made of insulating material to ensure insulation from the ground and eliminate safety hazards during the test process; the conductive circuit uses a conductive copper rod to avoid test abnormalities and risks that may be caused by poor contact.

[0033] Existing electronic sensor testing methods use external mounting on the circuit breaker body, which has many problems such as laborious lifting, complex installation, small number of tests, low test efficiency, and potential safety hazards. While achieving the same test function, this test fixture is lightweight, easy to lift and move, and reduces the labor intensity during the test process.

[0034] The design of the conductive rod 2 and the bottom bracket 3 makes the installation and removal of each sensor simple and quick, thereby improving the test efficiency.

[0035] The test fixture design allows for simultaneous installation and testing of multiple electronic sensors, significantly increasing test volume and efficiency.

[0036] In some embodiments, as Figure 1 and 2As shown, several mounting components are divided into two groups and arranged on opposite sides of the main frame 1. The bottom bracket 3 is connected to the main frame 1 with adjustable displacement. The bottom bracket 3 is designed to be adjustable to accommodate sensors of different heights. The two mounting components are divided into two groups, so two sets of electronic sensors can be installed and tested simultaneously, such as conventional and plateau types, thereby shortening the testing cycle and improving production efficiency.

[0037] In some embodiments, two mounting assemblies are symmetrically disposed on either side of the main frame 1, and the conductive rods 2 of the two mounting assemblies are coaxially fixedly connected and pass through the main frame 1. Coaxially fixing the conductive rods 2 of the two symmetrical mounting assemblies enhances the structural stability of the test fixture and simplifies the manufacturing and installation process of the test fixture.

[0038] In some embodiments, two flat pads 5 are connected to both ends of the conductive rod 2 to increase the contact area between the conductive rod 2 and the sensor to be tested, thereby improving the conductivity. The addition of the flat pads 5 reduces the effects of poor contact and ensures the continuity and accuracy of the test process.

[0039] In some embodiments, the main frame 1 includes several vertically arranged mounting rods 101, each conductive rod 2 being connected to a corresponding mounting rod 101. The conductive rod 2 is provided with external threads, one end of which passes through the mounting rod 101. The conductive rod 2 is connected to two nuts 6 located on either side of the mounting rod 101 and is secured to the mounting rod 101 by the two nuts 6. The cooperation between the external threads and the nuts 6 makes the connection between the conductive rod 2 and the mounting rod 101 more stable and reliable, reducing vibration and deflection during testing and improving test stability. The use of nuts 6 to secure the conductive rod 2 makes disassembly and replacement of the conductive rod 2 more convenient and quick.

[0040] In some embodiments, the main frame 1 includes several horizontally arranged crossbars 102, each of which connects at least two mounting rods 101 to provide enhanced structural support. The addition of crossbars 102 enhances the horizontal stability of the main frame 1, allowing the test fixture to carry heavier sensors under test.

[0041] In some embodiments, the main frame 1 includes a bottom plate 103, which connects the lower ends of all the mounting rods 101 to provide stable support. The bottom plate 103 provides a larger support area and enhances the stability of the entire test fixture.

[0042] In some embodiments, the bottom bracket 3 includes a vertical plate 301 with a waist-shaped hole 7 formed therein. The vertical plate 301 is fixed to the mounting rod 101 by bolts passing through the waist-shaped hole 7, and can be adjusted up and down relative to the mounting rod 101. This design allows the test fixture to accommodate sensors of different heights, improving its versatility and adaptability.

[0043] In some embodiments, the bottom bracket 3 includes a horizontal plate 302. A U-shaped groove 8 is provided at one end of the horizontal plate 302, distal from the main support, for supporting and positioning the bottom of the electronic sensor under test. The U-shaped groove 8 facilitates insertion of the bottom of the electronic sensor under test, provides a more stable installation, reduces drift during testing, and improves test accuracy.

[0044] In some embodiments, a clamp is provided at one end of the terminal block 4, which is connected to the conductive rod 2 and fixed by bolts, so as to facilitate the disassembly, assembly and replacement of the terminal block 4 and reduce maintenance costs.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
