The CJ19 series AC contactors are professional products developed by Geyue Electric for the specific conditions of power capacitor switching. Compared with traditional AC contactors, this series has been deeply optimized in terms of anti-surge current, contact lifespan, energy saving and consumption reduction. They are particularly suitable for dynamic reactive power compensation systems with frequent switching and can effectively solve the problems of contact sticking, burning, and short lifespan that traditional contactors often encounter when switching power capacitor. In the following, we will analyze the core technical features of CJ19 series contactors.
The CJ19 series contactor innovatively adopts a magnetic latching double coil structure design, and achieves efficient and energy-saving operation through a unique electromagnetic-permanent magnet composite working principle. During the working process, the pull-in coil is energized to generate electromagnetic force only at the moment of contactor action (about 15-20ms), and the power is immediately cut off after the contact is closed or disconnected; in the holding stage, the pull-in coil relies on the constant magnetic field generated by the high-performance NdFeB permanent magnet to maintain the contact state, completely eliminating the energy loss caused by the need for traditional contactors to be continuously powered on to maintain the pull-in. This innovative working mode keeps the overall power consumption of the product below 3W, which is more than 85% lower than that of conventional contactors, greatly reducing the power consumption of users in long-term use. At the same time, due to the elimination of the coil heating problem caused by continuous power-on and the use of a specially designed low-wear mechanical structure, the mechanical life of this series of contactors has reached a breakthrough of 2 million operations, which is more than 6 times that of ordinary contactors (usually 300,000 times), and is particularly suitable for dynamic reactive power compensation occasions that require frequent switching. In addition, this design also significantly reduces the coil temperature rise (≤55K), further improving the reliability and service life of the product in high temperature environments.

Magnetic latching double-coil structure:
The CJ19 series contactor innovatively adopts a magnetic latching double coil structure design, and achieves efficient and energy-saving operation through a unique electromagnetic-permanent magnet composite working principle. During the working process, the pull-in coil is energized to generate electromagnetic force only at the moment of contactor action (about 15-20ms), and the power is immediately cut off after the contact is closed or disconnected; in the holding stage, the pull-in coil relies on the constant magnetic field generated by the high-performance NdFeB permanent magnet to maintain the contact state, completely eliminating the energy loss caused by the need for traditional contactors to be continuously powered on to maintain the pull-in.

In addition, this design also significantly reduces the coil temperature rise (≤55K), further improving the reliability and service life of the product in high temperature environments.
Vacuum arc extinguishing technology:
The vacuum arc extinguishing technology used in the CJ19 series contactor represents a major technological innovation in the field of capacitor switching. During the capacitor switching process, due to the characteristics of the capacitive load, the system will generate an instantaneous surge current of up to 20-40 times the rated current, accompanied by a strong arc discharge phenomenon. Under this working condition, the arc duration of the traditional contactor can reach 5-10ms, causing the contact surface temperature to instantly rise to more than 3000℃, which will cause serious metal evaporation and contact ablation. To solve this industry problem, the CJ19 series innovatively adopts military-grade vacuum arc chamber technology. The three-stage molecular pump vacuuming process adopted by Geyue Electric maintains the vacuum degree inside the arc chamber at the order of 10^-3Pa. The gradient composite CuCr50 contact material combined with the special contact slot design not only ensures excellent conductivity, but also improves the arc ablation resistance by more than 3 times. The built-in axial magnetic field coil of the contactor generates a directional magnetic field during the disconnection process, which makes the arc rotate and diffuse rapidly to avoid local overheating.
High-reliability contact materials:
The CJ19 series contactor uses the independently developed AgSnO₂-In₂O3 nanocomposite contact material for contact materials. This innovation has brought the reliability of capacitor switching contactors to a new level. As the most critical component of the contactor, the performance of the contact directly determines the electrical life and operating stability of the equipment. Although traditional AgCdO contact materials have good conductivity, they are prone to welding when frequently switching capacitive loads, and there are environmental pollution problems. Our material scientists have solved this industry problem through the following technological innovations: In terms of raw material ratio, we use a special ratio of silver matrix (purity 99.99%) composite 12% SnO₂ and 3% In₂O3. Through nano-level dispersion strengthening technology, the oxide particles are evenly distributed in the silver matrix, and the particle size is controlled in the range of 50-80nm. In terms of preparation technology, we use vacuum melting-gas atomization powder making combined with hot isostatic pressing technology to ensure that the material density reaches more than 98.5% while maintaining excellent thermal conductivity (thermal conductivity ≥ 360W/m·K). On the working surface of the contact, we use laser micro-texturing technology to form a regular micro-concave and convex structure, which not only increases the effective contact area, but also provides a good arc diffusion channel. CJ19's AgSnO₂-In₂O3 composite contacts have excellent resistance to welding and electrical conductivity. They can still maintain low contact resistance when frequently switching high capacitive loads, and the electrical life can reach more than 500,000 times, greatly reducing maintenance costs.
