Isolation switch is one of the most commonly used equipment in the power system, mainly used to isolate voltage during equipment or line maintenance to ensure safety. It cannot disconnect load current and short-circuit current, and should be used in conjunction with circuit breakers. During a power outage, open the circuit breaker first and then the isolation switch. When delivering power, close the isolation switch first and then the circuit breaker.Purpose and execution standardsThis product is an outdoor high-voltage transmission equipment with a three-phase AC frequency of 50Hz. It is used to disconnect or connect high-voltage lines without load, in order to replace and change the operation mode of high-voltage lines, and to implement safe electrical isolation for high-voltage electrical equipment such as busbars and circuit breakers during maintenance. This product model is formulated in accordance with the provisions of JB/T8754-1998 "Method for Compilation of High Voltage Switchgear Models". This product complies with standards such as GB1985-2004 "AC High Voltage Isolation and Grounding Switches" and DL/T486-2000 "Technical Conditions for Ordering AC Isolation and Grounding Switches", and also meets the relevant regulations on ordering high-voltage isolation switches issued by State Grid Corporation of China for improvement. Important parameters and configuration methods that are not clearly defined in this standard. Revise and implement according to the requirements of GB11022-2000 General Technical Conditions for High Voltage Switchgear.
1. This product is a double column horizontal fracture center opening type, and can be equipped with grounding switches on one or both sides. The isolation switch with 90 ° transmission adopts CS17 manual operation mechanism for three-pole linkage operation; The isolation switch with a 180 ° transmission adopts a C) 6 manual operating mechanism for three-pole linkage operation; The grounding switch adopts a CS17G manual operating mechanism with three-pole linkage operation.
2. The isolation switch belongs to the double column V-shaped horizontal opening type, and each single pole is composed of a base, pillar insulators, outlet sockets, and contacts. It is installed on the bearings at both ends of the base with two supports and two pillar insulators at an angle of 50 °, perpendicular to the base. The main electrical components are installed above the two pillar insulated porcelain bottles, and rotate about 90 ° with the support of the Gui insulated porcelain bottle holder.
3. The soft connections of the copper braided tape in the outlet socket are respectively fastened to the conductive rod and the wiring board, which is used by the user to connect the circuit.
4. The contact fingers of the middle contact part are assembled in pairs, using external pressure or self operated contact fingers, which are in the form of turn-on type to reduce wear between the contact head and the contact fingers during opening and closing, and improve the service life.
5. When the isolation switch is equipped with a grounding switch, the interlocking between the main electrical circuit and the grounding switch is ensured by the fan-shaped and arc-shaped plates on the base. When the main electrical circuit is closed, the grounding switch cannot be closed, and when the grounding switch is closed, the main electrical circuit cannot be closed.
1. The isolation switch adopts a double column center open and contact turn in structure, which has the ability to automatically clean the contacts and improve contact reliability;
2. The touch finger is made of new materials with high strength, high conductivity, and high elasticity. By relying on the elastic force of the contact finger itself to clamp the contact, the vicious cycle of reduced contact clamping force, increased contact resistance, and intensified contact heating caused by spring corrosion and thermal annealing is avoided;
3. The rotating part of the isolation switch is designed according to the requirement of no installation. The rotating seat is designed as a sealed structure, preventing water vapor, dust, and harmful gases from entering, ensuring that the bearings and molybdenum disulfide lithium grease always work in a good environment. The bearings never rust, the grease cannot be lost, and it never dries up. This ensures that the operating torque of the isolation switch does not increase after long-term operation. Adopting a stainless steel shaft pin and an oil-free white lubricating shaft bearing matching mechanism; The steel parts are hot-dip galvanized to ensure flexible, lightweight, reliable, and never corroded operation of the isolation switch.
1. All parts are treated with hot-dip galvanizing technology for corrosion prevention. Parts that cannot be guaranteed to rotate in accordance with the requirements are generally made of stainless steel. Fasteners below M8 are made of stainless steel, while the rest are hot-dip galvanized.
2. The conductive part of the copper tube is soft connected, and the middle contact is a "handshake" type white force contact finger. The single spring external pressure type has no current passing through. The isolation switch only has one contact point in the middle, and the rest are made of soft contactConnect fixed connections.A adopts a new contact structure, fixing one end of the contact piece to the contact base. By relying on the deformation of the contact piece and the contact pressure generated by the spring, the sliding contact at the end of the contact finger is changed to fixed contact, improving the reliability of conductivity;b. Change the touch finger spring to an external type to avoid spring diversion;On site users do not need to weld or prepare auxiliary materials, only provide installation brackets (indicate whether brackets are included and height when ordering)
3. The rotating part is equipped with a self-lubricating sleeve, which does not require lubricating grease
4. The main wiring terminal is a flat panel type.
5. The pillar insulators used for switches have high strength density, stability and reliability. The formula is made of high-strength porcelain, which reduces the dispersion of product strength and increases the tensile strength of the product. When designing the structure, there is already a large strength reserve for the product, ensuring its stability and reliability during operation.
