背景技术Background technique
上三工位环网柜是指三工位隔离开关设置在断路器的上方的环网柜,采用上三工位隔离开关的柜体要实现接地操作时,需要上三工位隔离开关处于接地状态和断路器合闸同时满足,根据GB/T3906标准五防联锁要求,只有柜体处于接地状态时,电缆室门才能打开,这就要求设计时需要增加上三工位隔离开关对电缆室门联锁和断路器对电缆室门联锁。此外,现有柜体上的电缆室门包括铰接式电缆室门和上提式电缆室门,为了满足燃弧要求,柜体上的电缆室门多采用上提式电缆室门,上提式电缆室门上设有L形的卡扣,用于与柜体上的卡槽实现配合,需要打开电缆室门时上需要先上提电缆室门,使卡扣和卡槽解除配合,电缆室门即可打开。The upper three-station ring main unit refers to a ring main unit in which the three-station isolating switch is set above the circuit breaker. When the cabinet using the upper three-station isolating switch is to be grounded, the upper three-station isolating switch needs to be in the grounding position. status and circuit breaker closing at the same time. According to the five-proof interlocking requirements of the GB/T3906 standard, the cable room door can only be opened when the cabinet is in a grounded state. This requires adding an upper three-station isolation switch to the cable room during the design. Door interlock and circuit breaker interlock the cable room door. In addition, the cable room doors on the existing cabinets include hinged cable room doors and lift-up cable room doors. In order to meet the arcing requirements, the cable room doors on the cabinets mostly use the lift-up cable room door. There is an L-shaped buckle on the cable room door, which is used to match the slot on the cabinet. When you need to open the cable room door, you need to lift the cable room door first to release the buckle from the slot. The door will open.
现有技术中,上三工位隔离开关对电缆室门联锁和断路器对电缆室门联锁是通过分开设置的接地联锁机构和断路器联锁机构实现的,接地连锁机构用于实现三工位隔离开关与电缆室门的联锁,包括连接在上三工位的分合闸指示轴上的第一凸轮和与第一凸轮对应的第一顶杆,第一顶杆的下端与电缆室门对应,第一顶杆在第一凸轮转动时上下动作,实现对电缆室门的限位,防止电缆室门被上提打开。断路器连锁机构用于实现断路器与电缆室门的联锁,包括设置在断路器操动机构分合闸指示轴上的第二凸轮和与第二凸轮对应的第二顶杆,第二顶杆的下端与电缆室门对应,第二顶杆在第二凸轮转动时上下动作,实现对电缆室门的限位,防止电缆室门被上提打开。In the prior art, the interlocking of the cable room door by the upper three-station isolating switch and the interlocking of the cable room door by the circuit breaker are realized through separately set grounding interlocking mechanisms and circuit breaker interlocking mechanisms. The grounding interlocking mechanism is used to realize The interlocking of the three-station isolating switch and the cable room door includes a first cam connected to the opening and closing indicating shaft of the upper three stations and a first ejector corresponding to the first cam. The lower end of the first ejector is connected to the first cam. Corresponding to the cable room door, the first push rod moves up and down when the first cam rotates to limit the cable room door and prevent the cable room door from being lifted up and opened. The circuit breaker interlocking mechanism is used to realize the interlocking of the circuit breaker and the cable room door, and includes a second cam provided on the opening and closing indicating shaft of the circuit breaker operating mechanism and a second push rod corresponding to the second cam. The lower end of the rod corresponds to the cable room door, and the second push rod moves up and down when the second cam rotates to limit the cable room door and prevent the cable room door from being lifted up and opened.
现有技术中的接地联锁机构和断路器联锁机构在使用时,如果发生误操作,上提电缆室门时防止电缆室门开启的力是由相应的顶杆实现,由于第一、第二凸轮与电缆室门距离较远,第一、第二凸轮与电缆室门之间顶杆的长度较长,顶杆的径向尺寸受环网柜的空间限制也比较细,使得顶杆在受到较大上提力时会发生弯曲变形,从而导致电缆室门被误开启,可靠性较差。When the grounding interlocking mechanism and the circuit breaker interlocking mechanism in the prior art are used, if misoperation occurs, the force to prevent the cable room door from opening when lifting the cable room door is achieved by the corresponding push rod. Since the first and second The distance between the second cam and the cable chamber door is far, the length of the ejector rod between the first and second cams and the cable chamber door is long, and the radial size of the ejector rod is limited by the space of the ring main unit and is relatively thin, making the ejector rod in When subjected to a large lifting force, bending deformation will occur, causing the cable room door to be opened by mistake, resulting in poor reliability.

Correspondingly, the first transmission mechanism also includes a toggle piece fixed on the opening and closing indicating shaft or the opening and closing operating shaft of the three-station isolating switch operating mechanism. The toggle piece is used to operate the three-station isolating switch operating mechanism. During the grounding operation, the grounding interlocking swing arm is toggled to drive the grounding interlocking stopper to rotate to the unlocking position. When the three-station isolating switch operating mechanism performs isolation opening and closing, the toggle piece and the grounding interlocking swing arm are separated from each other. .

The circuit breaker interlocking arm is drivingly connected to the opening and closing indicating shaft or the opening and closing operating shaft of the circuit breaker operating mechanism. Both ends of the circuit breaker transmission connecting rod They are respectively hinged with the circuit breaker interlock arm and the circuit breaker interlock stop. The circuit breaker interlock arm is used to drive the circuit breaker interlock stop through the circuit breaker transmission connecting rod during the closing action of the circuit breaker operating mechanism. Rotate to the unlocking position, and during the opening action of the circuit breaker operating mechanism, the circuit breaker transmission connecting rod drives the circuit breaker interlocking stopper to rotate to the locking position.
有益效果:由于断路器联锁挡块处于解锁位时只需要和断路器操动机构的合闸状态对应,断路器联锁挡块处于锁止位时只需要和断路器操动机构的分闸状态对应,对应关系相对简单,第二传动机构采用断路器传动连杆与断路器联锁拐臂这种结构,可以在保证传动稳定,同时这种结构也相对简单,方便组装。Beneficial effects: Since the circuit breaker interlocking block only needs to correspond to the closing state of the circuit breaker operating mechanism when it is in the unlocking position, and when the circuit breaker interlocking block is in the locking position, it only needs to correspond to the opening of the circuit breaker operating mechanism. The corresponding state is relatively simple. The second transmission mechanism adopts a structure such as a circuit breaker transmission link and a circuit breaker interlocking arm, which can ensure stable transmission. At the same time, this structure is relatively simple and easy to assemble.
