Problems solved by technology

The electromagnet used in this type of switch needs enough space to displace the slidable iron core, so the trigger structure is relatively large, which makes the switch structure unable to be very compact.
At the same time, because the electromagnet is directly connected to the discharge electrode, it is easy to cause insulation damage

Embodiment Construction

[0025] The working principle of the invention is: when the switch works, the anode is at high potential and the cathode is at low potential. When the driving electromagnet is energized, a strong magnetic field is generated; the strong magnetic field passes through the brass cathode and attracts the carbon steel sliding electrode on the opposite anode to the surface of the cathode; the switch is turned on. When the driving electromagnet is powered off, the strong magnetic field disappears; the sliding electrode leaves the cathode under the action of the reset spring and returns to its original position; the switch is turned off. The present invention is further described below in conjunction with accompanying drawing:

[0026] like figure 1 As shown, the control isolation type high-voltage mechanical switch for the invention includes an anode, a cathode 5, and an outer insulating cylinder 8. The outer insulating cylinders 8 are arranged in pairs on both sides. The anode, the ...

Abstract

The invention discloses a control isolated form high-pressure mechanical switch which comprises a positive pole, a negative pole and outer insulating cylinders. The outer insulating cylinders are placed on two sides in pairs; the negative pole is connected on the inner rims of the upper ends of the outer insulating cylinders, and the positive pole is connected on the inner rims of the lower ends of the insulating cylinders; the positive pole, the negative pole and the insulating cylinders form a seal working cavity, and transformer oil is filled in the cavity; and the negative pole is provided with a groove with an upward opening, and a driving electromagnet is covered in the groove.

Description

technical field [0001] The invention belongs to a control isolation type high-voltage mechanical switch, in particular to a low-inductance fast-leading electromagnetic-driven mechanical switch for a compact electromagnetic pulse simulator. Background technique [0002] The switch is a key device in the field of pulsed power technology, which connects the energy storage device and the load. The performance of the switch affects the rise time, shape and amplitude of the output voltage waveform. High-voltage switches used in the field of pulse power include gas switches, vacuum switches, semiconductor switches, mechanical switches, etc. Different applications have different requirements for switch performance and types. In the compact electromagnetic pulse source, the switch is required to have low inductance, high withstand voltage, compact structure, simple and reliable control, etc. [0003] As a kind of high-voltage switch, the mechanical switch has been widely used in th...
