Problems solved by technology

[0002] At present, the existing high-voltage relays on the market generally use vacuum media. This type of relay is characterized by small contact resistance and can pass large currents. However, contact adhesion is prone to occur when the capacitor is connected to charge and discharge the capacitor, which affects the relay. service life

Embodiment Construction

[0018] In conjunction with the accompanying drawings, the present invention is described in detail, but the scope of protection of the present invention is not limited to the following examples, that is, all simple equivalent changes and modifications made with the patent scope of the present invention and the content of the specification are still patents of the present invention. covered.

[0019] Such as figure 1 As shown, a gas-filled high-voltage relay includes a first insulating and sealed casing 1 , contacts are provided in the first insulating and sealed casing, and high-pressure gas 10 is filled in the first insulating and sealed casing. Filling the relay with high-pressure gas can improve the ability of the relay to withstand pulse current when it is connected to a capacitive load, eliminate the influence of contact bounce on the discharge current waveform, and improve the connection life.

[0020] Preferably, a second insulating and sealing case 2 is provided outsi...

Abstract

The invention discloses an inflatable type high-voltage relay. The inflatable type high-voltage relay comprises a first insulating sealing shell; a contact is arranged inside the first insulating sealing shell; and the interior of the first insulating sealing shell is inflated with high-pressure gas. Since the interior of the relay can be inflated with the high-pressure gas, a capability of the relay to bear pulse current when a capacitive load is switched on can be improved, and influence of contact bounce on discharge current waveform can be eliminated, and a switch-on service life can be prolonged.

Description

technical field [0001] The invention relates to a high-voltage relay, in particular to an air-filled high-voltage relay. Background technique [0002] At present, the existing high-voltage relays on the market generally use vacuum media. This type of relay is characterized by small contact resistance and can pass large currents. However, contact adhesion is prone to occur when the capacitor is connected to charge and discharge the capacitor, which affects the relay. service life. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a gas-filled high-voltage relay, which can withstand a larger pulse current and higher voltage when a capacitive load is connected, and has a longer service life. [0004] The technical solution adopted by the present invention to solve the technical problem is: an inflatable high-voltage relay, including a first insulating and sealing shell, and contacts are arranged in the first i...
