Problems solved by technology

[0002] At present, the DC relays on the market are compact in structure and small in size, but the working voltage is also low, while the high-voltage (up to 25kV.DC.) kilovolt-level high-voltage DC relays are often bulky, which limits their use.

Embodiment Construction

[0028] Such as figure 1 As shown, an example of the invention includes a housing, a contact block assembly, a pivot armature assembly, and an electromagnetic drive assembly. The shell includes a ceramic sealing cover 1 and a plastic shell 2, and the plastic shell 2 has mounting ears for easy installation.

[0029] Such as Figure 4 As shown, the contact group assembly includes a NO normally open contact 11 , an NC normally closed contact 12 , a COM common terminal 13 and a movable contact piece 14 . The NO contact 11, the NC contact 12 and the COM 13 are welded together with the ceramic sealing cover 1 by brazing. The moving contact piece 14 is fixed on the transmission rod 16 through the clip spring 15 . One end of the moving contact piece 14 is stuck in the slot of the COM end 13 located in the sealed chamber, and the other end is between the NO and NC contacts.

[0030] Such as Figure 4 As shown, the pivot armature assembly includes a drive rod 16 , an insulator 17 , ...

Abstract

The invention discloses a pivot armature type high-voltage direct-current relay comprising a contact group assembly, a pivot armature assembly, an electromagnetic drive assembly and a shell part. The contact group assembly consists of four parts: a normally-opened contact, a normally-closed contact, a COM terminal and a movable contact piece; the movable contact piece is fixed on a transmission rod by a clamp ring; and one end of the movable contact piece is limited in a clamp groove of the COM terminal and the other end is arranged between the normally-opened contact and the normally-closed contact. The movable contact piece is driven by the pivot armature assembly to oscillate between an NO contact and an NC contact; the pivot armature oscillates inwardly under the electromagnetic force and oscillates outwardly under the counter force of the spring. According to the invention, the contacts are made of tungsten-molybdenum alloy materials, so that the anti-welding performance is excellent; a sealed chamber is vacuumized, so that the compression and insulation performances are good; and the transmission mechanism has a displacement amplification function and the breaking speed is fast. The high-voltage direct-current relay has the high mechanical reliability and can adapt to various contact structures. With a displacement amplification mechanism, the breaking speed increases, so that large voltage switching can be realized well; and on the basis of the winding design, easy replacement outside the sealed chamber is realized.

Description

technical field [0001] The invention relates to a pivotal armature type high voltage direct current relay. Background technique [0002] At present, the DC relays on the market are compact in structure and small in size, but their working voltage is also low, while the kilovolt-level high-voltage DC relays with high working voltage (up to 25kV.DC.) are often bulky, which limits their use. The invention relates to a pivotal armature type high-voltage DC relay, which can withstand 5KV DC high voltage, adopts a compact structure, effectively reduces its size, reduces and saves its installation space, and has practicability. Contents of the invention [0003] The purpose of the present invention is to provide a pivotal armature type high-voltage direct current relay, which adopts a compact structure design and minimizes its volume. [0004] The technical solution of the present invention is: a pivot armature type high-voltage direct current relay, which is characterized in th...
