Description

旋转式双断点开关接触系统接线改良结构Rotary double breakpoint switch contact system wiring improved structure 技术领域Technical field
本发明属于隔离开关技术领域,,具体讲就是涉及一种旋转式双断点开关接触系统接线改良结构。The invention belongs to the technical field of isolating switches, and in particular relates to a wiring improved structure of a rotary double-breakpoint switch contact system.
背景技术Background technique
隔离开关是高压开关电器中使用最多的一种电器,隔离开关的主要特点是无灭弧能力,只能在没有负荷电流的情况下分、合电路。隔离开关用于各级电压,用作改变电路连接或使线路或设备与电源隔离,它没有断流能力,只能先用其它设备将线路断开后再操作。一般带有防止开关带负荷时误操作的联锁装置,有时需要销子来防止在大的故障的磁力作用下断开开关。在电路系统中,当线路出现故障或者需要检修时,断路器跳闸,此时隔离开关起到了切断小电流或者提供明显端口的作用,以保障维修或者检修时工作人员的安全。通常情况下,隔离开关有两种形式,敞开式和气体绝缘金属封闭式,敞开式隔离开关直接暴露在空气中,分闸时可看到明显断口,但体积大、较为笨重。气体绝缘金属封闭式隔离开关体积小、可靠性高,得到了广泛应用,气体绝缘金属封闭式隔离开关一搬包括三个隔离开关单相,每个隔离开关单相均包括筒体,各筒体中均设置有动触头、静触头和驱动动触头动作的驱动机构,驱动机构大多数采用电驱动,然而由于气体绝缘金属封闭式隔离开关的封闭性,操作人员不能直接观察和明显感受其是否处于分断状态。The isolating switch is the most used one in the high-voltage switchgear. The main feature of the isolating switch is that it has no arc-extinguishing capability, and can only divide and close the circuit without load current. The isolating switch is used for voltages at various stages. It is used to change the circuit connection or to isolate the line or equipment from the power supply. It has no current-breaking capability and can only be disconnected before operation by other equipment. Generally, there is an interlock device that prevents the switch from being erroneously operated with a load, and sometimes a pin is required to prevent the switch from being opened under the action of a large fault magnetic force. In the circuit system, when the line fails or needs to be repaired, the circuit breaker trips. At this time, the isolating switch acts to cut off the small current or provide an obvious port to ensure the safety of the staff during maintenance or overhaul. Under normal circumstances, the isolating switch has two forms, open type and gas-insulated metal-enclosed type, the open type isolating switch is directly exposed to the air, and the obvious break can be seen when opening, but it is bulky and cumbersome. The gas-insulated metal-enclosed isolating switch has small volume and high reliability, and has been widely used. The gas-insulated metal-enclosed isolating switch includes three isolation switches and one phase, and each of the isolation switches includes a cylinder, and each cylinder The moving mechanism, the static contact and the driving mechanism for driving the moving contact are provided in the middle, and most of the driving mechanism is electrically driven. However, due to the sealing property of the gas insulated metal-enclosed isolating switch, the operator cannot directly observe and obviously feel Whether it is in a disconnected state.
目前市场上有一种常见的旋转式双断点隔离开关,其接触系统的接线只能采取一个方向进线的方式进行,缩小了旋转式双断点隔离开关的适用范围,在 某些特殊场合需要改变隔离开关的安装位置时,无法调整接线方向,导致隔离开关无法适用。At present, there is a common rotary double-breakpoint isolating switch on the market. The wiring of the contact system can only be taken in one direction, which reduces the applicable range of the rotary double-breakpoint isolating switch. When it is necessary to change the installation position of the isolating switch in some special occasions, the wiring direction cannot be adjusted, and the isolation switch cannot be applied.
发明内容Summary of the invention
本发明的目的是针对现有的旋转式双断点隔离开关接线方向单一的技术缺陷,提供一种旋转式双断点开关接触系统接线改良结构,通过对接线方式的改进使旋转式双断点隔离开关接触系统的接线方向能够灵活改变,满足了隔离开关现场安装的需要。The object of the present invention is to provide a rotary double-breakpoint switch contact system wiring improvement structure for the single technical defect of the existing rotary double-breakpoint isolation switch wiring direction, and to make the rotary double breakpoint by improving the wiring mode. The wiring direction of the isolating switch contact system can be flexibly changed to meet the needs of on-site installation of the isolating switch.
