With the rise of green energy, high-capacity relays are widely used in high-voltage DC loads such as vehicles, photovoltaics, and charging piles. In view of the above application scenarios of high-voltage DC loads, it is often necessary to set auxiliary contacts to monitor the status of the main contacts and perform low-voltage Linkage control to improve the safety and reliability of electrical equipment.
传统继电器的主要通过在陶瓷腔体的顶部增加了一组辅助触点，实现对主触头的监测，其结构较为简单，但由于主触头和辅助触点同时分布在陶瓷顶部，高低负载隔离效果差；当主触头开断负载时，电弧容易窜到辅助触点，造成高低负载连通，甚至烧毁辅助触点，存在安全隐患；主触头飞溅的金属颗粒容易污染辅助触点，辅助触点的可靠性无法保证；此结构辅助触点的开关逻辑单一，与主触头同步通断，难以实现相反逻辑下的动作；此结构的辅助触点形式单一，仅为常开型结构，难以满足继电器对常闭型辅助触点的需求；辅助触点尺寸较大，通常只能在陶瓷腔体的顶部设置一组，当需要设置多组辅助触点时，继电器结构体积增大，结构复杂；此外，传统继电器的辅助触点与主触头之间缺乏有效隔离，当主触头燃弧烧蚀时，金属颗粒等飞溅物可能会溅射到辅助触点上，进而造成辅助触点失效，从而影响继电器的可靠性，不利于提升产品的市场竞争力。The traditional relay mainly monitors the main contacts by adding a set of auxiliary contacts on the top of the ceramic cavity. Its structure is relatively simple, but because the main contacts and auxiliary contacts are distributed on the top of the ceramic at the same time, the high and low loads are isolated. The effect is poor; when the main contact breaks the load, the arc is easy to reach the auxiliary contact, causing high and low loads to be connected, and even burning the auxiliary contact, which is a safety hazard; the metal particles splashed by the main contact are easy to contaminate the auxiliary contact. The reliability of the auxiliary contact cannot be guaranteed; the switching logic of the auxiliary contact of this structure is single, and it is on and off synchronously with the main contact, so it is difficult to realize the action under the opposite logic; the auxiliary contact of this structure has a single form and is only a normally open structure, which is difficult to meet The relay has a requirement for normally closed auxiliary contacts; the auxiliary contacts are large in size, usually only one set can be set on the top of the ceramic cavity. When multiple sets of auxiliary contacts need to be set, the structure of the relay increases in size and the structure is complex; In addition, there is a lack of effective isolation between the auxiliary contacts and the main contacts of traditional relays. When the main contacts are ablated by arcing, spatters such as metal particles may be sputtered on the auxiliary contacts, thereby causing the auxiliary contacts to fail. It affects the reliability of the relay and is not conducive to improving the market competitiveness of the product.
