Detailed Product Description: | An overview ZW8-12D / 630 series outdoor vacuum circuit breaker is three-phase AC 50Hz outdoor high voltage switchgear, and is mainly used for urban and rural network of 12KV system, as a sub, co-load current, overload current and short-circuit current use, can also be used for other similar places. 2, the use of environmental conditions 3.1 Ambient air temperature: + 40 ℃ - -30 ℃ 3.2 Altitude: ≤2000m 3.3 Pressure: ≤7000Pa (equivalent wind speed 34m / s) 3.4 degree of air contamination: Ⅲ grade 3.5 maximum daily temperature: ≤ 25 ℃ 3.6 non-recurrent severe vibration 3, the structure and working principle 3.1 breaker structure: made of conductive circuit breakers, insulation systems, seals, actuator and housing composition, the overall structure of the three-phase box. Conductive loop is formed by inlet, outlet conductive rod, soft links, dynamic and static end bearing, conductive clamp connection is made with the vacuum interrupter. Ceramic vacuum interrupter circuit breaker equipped with a series of newly developed outdoor air insulated vacuum circuit breaker dedicated interrupter. It uses CuCr angle arch goblet longitudinal magnetic field structure, ceramic big climb from the shell, with a small, high breaking capacity, low closure levels, good housing anti-condensation effects and other advantages. Breaker outer insulation is mainly achieved through the silicone rubber casing, with anti-contamination ability. Insulating air --DMC insulated cover box composite insulation, insulation material is mainly used DMC pressed into interrupter boxes, each phase interrupter installed in a separate insulated box, by closing the lid and the air gap insulation to achieve insulation purposes. Current transformer installed inside the circuit breaker for overcurrent and short circuit protection: the case has not yet containing a desiccant dehumidifier and release the pressure relief valve. Actuator fir L configuration using the new special spring mechanism, available electric energy storage, electric points, closing, we can use the manual storage and manual opening and closing. The circuit breaker can be built dry-voltage transformer and add infrared remote control device, enabling white equipment operating power and juice volume, and on-site hand-held remote control points, co-operation. The circuit breaker can also install outdoor isolating switch, consisting of a combination of switches, the switches have visible security fracture when disconnected. Load isolation switch can not be directly division, with reliable mechanical linkage between it and the breaker body. The circuit breaker can also be equipped with an independent reclosing control system so that the circuit breaker has 1-3 times reclosing operation function, you can also complete with electric load monitoring system. 5.2 Theorem: A circuit breaker is operated by operating mechanism (see Figure 1), institution or opening spring three-phase circuit breaker spindle rotation drive under. While pulling insulated operating rod 4 and the crank arm 5, the vacuum arc chamber movable contact 8 opened or closed, leaving the circuit breaker in the open or closed state. 6, lifting installation, commissioning: product during transport, not flip, tilt and shock measures to be taken. When lifting the circuit breaker needs to be hooked on both sides of the middle of the box four earrings, horizontal lift. Not hanging two rings on the cover, the rings are for lifting the lid when debugging hanging core used. Before installing the product appearance and mechanical properties to be checked. First, see if there is damage to the outside, box whether deformation. Then open the box, put the lid put on a shelf to watch at the bottom if there is loss of metal objects, such as solid pieces are loose. Mechanical properties such as checks, open the lid of each phase insulation, according to data presented in Table 2 mechanical properties inspection. Circuit breaker can measure distance and overtravel according to the method shown in Figure 2, in points, closing state measured as the difference between the X value of open distance, the difference between the value of Y is overrun. Adjust the X, Y value is to put longer or shorter insulated operating rod. |
