Xi'an ZW32-12F / 630-20 vacuum circuit breaker watchdog intelligent boundary switch external PT-Shaanxi Taikai High Voltage Switch Manufacturing Co., Ltd. ZW32-12 Overview ZW32-12 series outdoor AC high voltage vacuum circuit breaker (hereinafter referred to as "circuit breaker") ) Is a three-phase AC 50Hz outdoor high-voltage switchgear, which is mainly used in the 10kV outdoor distribution system of rural and urban power grids. It is used for splitting, combined load current, overload current and short circuit current; it can also be used in other similar places. ZW32-12 series outdoor AC high voltage vacuum circuit breakers meet the standards of ** GB 1984 "AC High Voltage Circuit Breakers" and International Electrotechnical Commission IEC 60056 "High Voltage AC Circuit Breakers". Shanghai Changkai Electric Co., Ltd. 2. Model and meaning of ZW32-12 3. Conditions of use of ZW32-12 3.1 Normal conditions of use a)
Ambient air temperature: -40 ℃ ～ + 40 ℃; b) Altitude: no more than 2000m; c) Ambient air can be polluted by dust, smoke, corrosive gas, steam or salt mist; d) Wind speed does not exceed 34m / s (Equivalent to 700Pa on the surface of the cylinder); e) Vibration or ground motion from the switchgear and control equipment is negligible; f) Pollution level: Class III. 3.2 ZW32-12 special use condition circuit breaker can be used under the normal use conditions different from the above, at this time, the user's requirements should be negotiated with the manufacturer, and a consistent opinion is obtained. 3.3 If the above normal use conditions are exceeded, the user and the manufacturer shall negotiate. 4. ZW32-12 technical parameters 4.1 Circuit breaker main technical parameters 4.2 Circuit breaker assembly adjustment parameters 4.3 CTB spring operating mechanism main technical parameters 4.4 ZW32 outdoor vacuum circuit breaker with isolating switch, in addition to meeting the requirements of Table 1 and Table 2, The disconnector part should also meet the requirements of Table 4. 5. Structural characteristics of ZW32-12 circuit breaker 5.1 ZW32 circuit breaker adopts a three-phase pillar structure, which has stable and reliable breaking performance, no risk of combustion and explosion, no maintenance, small size and weight Light and long service life. 5.2 The ZW32 circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve moisture resistance and anti-condensation performance, and is particularly suitable for use in severe cold or humid areas. 5.3
ZW32 three-phase pillars and current transformers adopt imported outdoor epoxy resin solid insulation, or adopt internal epoxy resin outsourcing silicone rubber solid insulation; have the characteristics of high and low temperature resistance, ultraviolet resistance, aging resistance and so on. 5.4 The ZW32 operating mechanism adopts a miniaturized spring operating mechanism, the energy storage motor has low power, and the opening and closing energy consumption is low; the mechanism transmission adopts a direct-acting transmission mode, with fewer parts and high reliability. The operating mechanism is placed in a sealed mechanism box, which solves the problem of corrosion of the operating mechanism and improves the reliability of the mechanism. 5.5 The opening and closing operation of ZW32 circuit breaker can be manual or electric operation and remote control operation. It can be matched with an intelligent controller to realize power distribution automation, and can also be combined with a reclosing controller to form an automatic recloser and a segmenter. 5.6 The ZW32 circuit breaker can be equipped with two-phase or three-phase current transformers for over-current or short-circuit protection, and can also provide current acquisition signals to the intelligent controller; according to user requirements, a current transformer for measurement can be added.
5.7 ZW32 circuit breakers can be equipped with three-phase linkage disconnectors. When the disconnector is in the open state, there is a visible break, and it has an anti-misoperation interlock device with the circuit breaker body. When the circuit breaker is in the closing position, the isolating switch cannot perform opening and closing operations; the circuit breaker can only be operated when the isolating knife is fully closed or fully opened. It can be installed with lightning insulator support insulators, which can be maintained and firmly installed on the special steel frame. The installation schematic diagram is shown in Figure 19. 8.6 The product is regularly inspected to check whether the circuit breaker is operating normally. For circuit breakers with isolating switches, the isolating switches are inspected twice a year, which includes checking whether the mechanical interlocking action between the isolating switch and the circuit breaker is normal, and injecting some grease into the moving parts. 9. ZW32-12 transportation, acceptance and storage 9.1 During transportation and transportation, it must be packed in a closed package and fixed. During transportation, it must not be overturned or tilted, and anti-vibration measures must be taken. When overhanging the circuit breaker body, the four lifting rings hooked on the box body shall not directly carry the epoxy insulation cylinder. When the super-hanging circuit breaker is equipped with an isolating switch, the center of gravity is biased to the isolating switch side, and it should be carried out slowly when lifting. 9.2 Acceptance After receiving the circuit breaker, the user should perform the following acceptance work: 1) Check whether the packaging is damaged; 2) Check whether the documents and accessories are complete according to the product packing list; 3) Check whether the technical parameters on the circuit breaker nameplate and product certificate Meet the order requirements. 9.3 Storage The circuit breaker should be stored in a dry, ventilated, moisture-proof, shock-proof and harmful gas-proof room. Long-term storage should regularly check whether the environment meets the requirements. Packing, unpacking and storage should be carried out in a dry room, and the products and various parts should be checked for completeness and conformity. 10. Common faults and troubleshooting methods Common faults and troubleshooting methods 11. Random documents and spare parts 11.1 ZW32-12 product certificate; 11.2 ZW32-12 circuit breaker instruction manual; 11.3 factory inspection report; 11.4 packing list; 11.5 secondary configuration Line drawing; 11.6 ZW32-12 operating mechanism instruction manual; 11.7 Random spare parts.
