Description

Technical Field

[0001] The utility model relates to the technical field of pulse switches, in particular to a high-power pulse switch tube contact with a long service life. Background Art

[0002] Pulse switching power supplies are different from linear power supplies. The switching transistors used in switching power supplies mostly switch between full-on mode (saturation zone) and full-closed mode (cut-off zone). Both modes have the characteristics of low dissipation. The transition between switches will have higher dissipation, but the time is very short, so it is more energy-saving and generates less waste heat. Ideally, the switching power supply itself does not consume electrical energy. Voltage regulation is achieved by adjusting the time when the transistor is turned on and off. On the contrary, in the process of generating output voltage, the transistor of the linear power supply works in the amplification zone, which also consumes electrical energy. The high conversion efficiency of the switching power supply is one of its major advantages. In addition, because the switching power supply operates at a high frequency, a small-sized and light-weight transformer can be used. Therefore, the switching power supply will be smaller in size and lighter in weight than the linear power supply.

[0003] The pulse switching power supply in the prior art is smaller in size and lighter in weight than the linear power supply, but the following problems exist in actual use: 1. The existing pulse switching power supply has a low power consumption of only less than 4KV and a short service life of less than 10,000 times; 2. Secondly, there is no protective component at the power connection end of the power supply, which is easy to wear, so a high-power pulse switching tube contact with a long service life is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems that the existing pulse switching power supply has low power consumption, only less than 4KV, short service life, less than 10,000 times, and no protection components at the power supply terminal, which is easy to wear, and a high-power pulse switch tube contact with a long service life is proposed.

[0012] Beneficial Effects

[0013] In the utility model, in the device, a contact with a flat top and a small semicircle on the lower large circle is adopted (the semicircular contact first conducts the pulse power supply to induce the positive large power current discharge) to improve the product performance, so that the service life of the power pulse switch tube increases from the original impact number of ≥300,000 times to ≥1 million times. The performance and service life of the product are greatly improved, and the application requirements are fully met.

[0014] In the utility model, the installation of the power connection terminal adopts a splicing type, the adapter is for power connection, and the interface on the outside is raised.
