Remote high-voltage pulse nanosecond switch applying insulating oil

Abstract

The invention relates to a remote high-voltage pulse nanosecond switch applying insulating oil. The remote high-voltage pulse nanosecond switch comprises an organic glass shell, an electrode disk, a cathode, an anode, a triggering electrode, an electromagnet, a refined rapeseed oil serving as an insulating medium and a remote triggering and controlling system. The cathode, the anode and the electrode disk are tightly fixed together through bolts; the head of an electromagnet shell is provided with a thread and is connected with the organic glass shell of the switch; the tail end of an electromagnet core is connected with the triggering electrode through an organic glass rod; and the remote triggering and controlling system consists of a wireless remote controller, a receiving antenna, a high-frequency receiving module packaged in a metallic shield shell, a decoding integrated circuit (IC), a driving circuit, a relay and a storage battery. According to the remote high-voltage pulse nanosecond switch, radio signals emitted from the controller are received by the antenna, transmitted to the high-frequency receiving module and decoded by the decoding IC, the relay is driven by the driving circuit to energize the electromagnet and push the triggering electrode to move towards a main electrode, so that quick high voltage discharging is safely, reliably and conveniently realized, and a pulse wave form of which the rising edge is a nanosecond level is formed.

Description

1. Technical field [0001] The invention relates to a remote-controlled oil-insulated high-voltage pulse nanosecond switch, in particular to an oil-insulated switch used for high-speed high-voltage wireless remote-controlled discharge in a high-voltage pulse source of a high-altitude nuclear explosion electromagnetic pulse (HEMP) simulator. 2. Background technology [0002] The high-voltage discharge switch is a key device in the electromagnetic pulse source. The high-voltage discharge switch in the existing high-voltage pulse source is divided into a gas switch and a liquid switch from the internal insulating medium of the switch, and a two-electrode switch and a three-electrode switch from the switch electrode structure. switch. [0003] The existing gas switch is to fill the switch gap with a certain pressure of gas, such as air, nitrogen, SF6 and so on. Among them, SF6 is relatively expensive, and its discharge products are also poisonous, so it cannot be discharged into...

Problems solved by technology

The existing three-electrode switch includes an anode, a cathode, and a trigger pole. The trigger pole is generally triggered by a pulse voltage, laser beam or electron beam provided by an external trigger source. This type of switch requires a higher trigger pulse voltage, or a laser beam , or electron beam, which is expensive and inconvenient to use
