Product Details
LW46-126 (145kV) / T3150-40 SF6 circuit breaker The circuit breaker adopts a three-phase porcelain bottle pillar structure, which is designed for outdoor use. The three phases are equipped with an SRCT36-C spring operating mechanism, which is arranged in the center and three phases are connected, so the appearance is novel and exquisite. The circuit breaker uses SF6 gas as the insulation and arc extinguishing medium. During operation, the three-pole SF6 gas of the circuit breaker should be connected, and the pressure and density are monitored by a pointer density relay. Due to the self-energy arc extinguishing principle and the optimized design in the circuit breaker motion system, the mechanical efficiency is effectively improved and the operating work is reduced to the minimum.
LW46-126 (145kV) / T3150-40 SF6 circuit breaker The overall structure of this type of circuit breaker is shown in Figure 1. The three poles are installed on a common base. The control cabinet is centrally hoisted under the base. The spring operating mechanism and control unit are installed in the cabinet. The output rod of the mechanism is connected to the crank arm of the middle phase. The three-phase SF6 gas is connected to the crank box of the A-phase and C-phase circuit breakers to perform opening and closing operations. The SF6 gas density relay is used to monitor the SF6 gas density in the circuit breaker (the density relay is within the allowable working range of the product and can be calibrated on site without disassembly. If it is necessary to disassemble and calibrate, it is necessary to pay attention to the correct assembly of the sealing ring at the joint end of the density relay to prevent leakage)
