Embodiment 1

[0022] Such as figure 1 As shown, it is a schematic diagram of a handcart valve device for a balanced DC fast circuit breaker provided in this embodiment, including a mounting plate 1 on which a first fixed slider guide rail 11 and a second fixed slider guide rail 12 are fixedly arranged. A sliding valve 2 is slidably connected between a fixed slider guide rail 11 and a second fixed slider guide rail 12, and a bottom limit stop is arranged on the mounting plate 1 at the lower end of the first fixed slider guide rail 11 and the second fixed slider guide rail 12 block 13, the sliding valve 2 is provided with a connecting rod fixing support 21, and the mounting plate 1 below the bottom limit block 13 is provided with a connecting rod support 15, and the connecting rod supporting member 15 passes through the connecting rod and the connecting rod fixing support 21 connections. The materials of the mounting plate 1 and the sliding valve 2 are insulating materials, the upper end of ...

Embodiment 2

[0026] This embodiment is a further improvement on the basis of Embodiment 1, wherein the material of the mounting plate 1 and the sliding valve 2 are both PC, which has good insulation performance and stability in use. An intermediate support rod 6 is arranged between the two first connecting rods 3, and the two ends of the intermediate supporting rod 6 are respectively connected to the side of the two first connecting rods 3 close to the connecting rod support 15, which can better stabilize the first connecting rod. At the same time, the rod 3 can keep the first connecting rod 3 stable in the process of receiving and transmitting force. The lower end of the mounting plate (1) is provided with a fixed block, and the fixed block is provided with a through hole; the lower end of the sliding valve (2) is fixedly provided with a valve locking mechanism (14); image 3 As shown, the valve locking mechanism (14) is an L-shaped metal object with openings on it. The valve locking mech...

Abstract

The invention discloses a balance type direct current rapid breaker truck's valve device which comprises installation plates. One side of the installation plate is fixedly provided with a first fixed sliding block guide rail while the other side is fixedly provided with a second fixed sliding block guide rail. Between the first fixed sliding block guide rail and the second fixed sliding block guide rail is connected a sliding valve. Both the installation plates at the lower ends of the first fixed sliding block guide rail and the second fixed sliding block guide rail are provided with bottom position limiting blocks. A valve locking mechanism is mounted on the installation plates of below the bottom position limiting blocks. The sliding valve is provided with a connection rod fixing component. The installation plates below the bottom position limiting blocks are provided with a connection rod supporting component. The connection rod supporting component is connected with the connection rod fixing component through the connection rod. The balance type direct current rapid breaker truck's valve device of the invention is convenient to use, raises the motion flexibility of a valve structure and makes the structure a more simplified one.

Description

technical field [0001] The invention belongs to the related field of switch cabinet control, and in particular relates to a handcart valve device for a balanced DC fast circuit breaker. Background technique [0002] With the process of urbanization and the rapid construction of power grids, the power system has been widely popularized. As a special unit in the power transmission and distribution system, the switch cabinet is more and more valued by users. Switchgear has many advantages, and it has been widely recognized and used in domestic and foreign markets. As a special unit in the switchgear, the valve mechanism not only plays a protective role, but also has a certain internal relationship with the switchgear to adapt to different circuit breaker handcarts. The cooperation between it and the handcart of the circuit breaker determines the electrical performance of the switchgear and the safe operation of the switchgear. [0003] The handcart valve mechanism is the con...
