[0006] In one embodiment, the positioning device further comprises a positioning hole, the positioning hole is formed in the positioning tooling plate, and the position of the positioning hole is matched with the position of the positioning opening on the circuit breaker flange.
[0007] In one embodiment, the positioning device further comprises a positioning pin, the positioning pin is matched with the positioning hole, and the positioning pin can simultaneously pass through the positioning hole and the positioning opening to fix the positioning tooling plate and the circuit breaker flange.
[0008] In one embodiment, the positioning hole is multiple, and the corresponding positioning pin is also multiple.
[0009] In one embodiment, the positioning device further comprises three insulating sleeves, the three insulating sleeves are arranged on the inner side of the three sleeves and are attached to the sleeves.

[0012] Compared with the prior art, the utility model has beneficial effects. Through the design of the positioning tool plate and the three sleeves, the problems of difficulty and low efficiency encountered in the installation process of the three-phase contact are effectively solved. First, the three round holes on the positioning tool plate are aligned with the three-phase contact seat, and each round hole corresponds to a sleeve, which can ensure that each three-phase contact is accurately aligned, and then the three-phase contact is sequentially placed in the corresponding sleeve. These sleeves not only guide the three-phase contact to be accurately positioned, but also play a certain limiting role, ensuring that deviation or misalignment does not occur during installation, thereby improving installation efficiency and quality, and the entire installation process is more convenient and fast, significantly improving work efficiency.

The structural contents mentioned in the following embodiment are all referred to the drawings.
[0019] Each exemplary embodiment of the utility model will be described below with reference to the accompanying drawings.
[0020] Embodiment 1, a positioning device 100 for installing three-phase contact of circuit breaker flange, as Figure 1As shown, the positioning device 100 includes a positioning tool plate 10 and three sleeves 11, and the positioning tool plate 10 is provided with three circular holes corresponding to the three-phase contact seat.
[0021] In embodiment 2, on the basis of embodiment 1, as Figure 2 As shown, the positioning device 100 further includes a positioning hole 13 and a positioning pin 14, the positioning hole 13 is provided on the positioning tool plate 10, and the position of the positioning hole 13 is matched with the position of the positioning opening on the circuit breaker flange. First, the positioning tool plate 10 is placed on the three-phase contact seat to ensure that the three sleeves 11 on the positioning tool plate 10 are aligned with the three-phase contact seat. Then, the positioning pin 14 is inserted through the positioning hole 13 and the positioning opening on the circuit breaker flange, so that the positioning device 100 can be stably placed on the circuit breaker flange.
[0022] Based on the above embodiments, the positioning device 100 further includes three insulating sleeves 12, which are arranged inside the three sleeves 11 and closely attached to the sleeves 11, and the insulating sleeves 12 can be made of polytetrafluoroethylene. By arranging three insulating sleeves 12 closely attached to the sleeves 11, effective isolation between electrical components is ensured, and the risk of short circuit is avoided, so that the installation of the three-phase contact is more secure and reliable. The insulating sleeves 12 are usually made of polytetrafluoroethylene, which has good insulation performance and soft characteristics, and can better protect the silver plating layer on the contact during installation to prevent damage.
[0023] Based on the above embodiments, the positioning device 100 further includes a welding plate 20 arranged between two adjacent sleeves 11 for fixing the two adjacent sleeves 11, forming a stable triangular structure, which can enhance the overall stability of the positioning device 100 and ensure the reliability and safety during installation.

[0025] During installation, the three-phase contact is accurately aligned with the corresponding three-phase contact seat, and this precise alignment not only simplifies the adjustment steps, but also avoids installation problems caused by misalignment. This process improves labor efficiency because it reduces rework time and labor input caused by adjustment errors. The entire process involves precise alignment, fastening connection and final detection of the three-phase contact and the contact seat, thereby realizing integrated efficient installation and debugging and ensuring the efficiency of the assembly process.
