Can be connected to the line, cut off the fault current and protection. Especially suitable for frequent operation, such as throwing and cutting capacitor group, control electric furnace transformer and high voltage motor, etc., can also be used as a contact. 2, structural features: circuit breaker main part of the set In the tree by the epoxy This structure can effectively prevent the external impact, due to environmental pollution and other external factors on the impact of the vacuum interrupter. Circuit breaker with ZMD1410 series of sealed ceramic or glass vacuum interrupter , The copper-chromium contact with a ring longitudinal magnetic field contact structure, breaking ability, low level of closure, long electrical life. Vacuum interrupter and insulation poke inside, so that the circuit breaker with maintenance-free, ***, no Explosion hazard, low noise, high insulation level. The operating mechanism for the spring energy storage operation mechanism, the body box is equipped with closing unit, the front panel with points, and buttons, hand can operate hole, spring energy status indicator And other institutions and the body before and after the layout into one, high transmission efficiency, good operating performance, suitable for frequent operation, can be installed in the removable or fixed switchgear. 3, the working principle: circuit breaker closing energy required by the spring storage Energy storage device can be completed by the external power supply motor can also be stored by the manual energy storage energy storage. After the completion of energy storage, energy storage signs show that "energy storage switch" Energy storage motor power supply, circuit breaker In the closing state, in the closing operation, regardless of hand press the "close" button or remote operation so that the closing electromagnet action, can make the circuit breaker closing. After the closing action is completed, the energy storage instructions The switch is reset and the motor is switched on again. The motor is re-energized. The closing sign shows that the switch is connected to the switch. In the opening operation, regardless of the hand, press the & ldquo; ; Button or remote operation so that the closing electromagnet action, can make the circuit breaker sub-gate, sub-gate action is completed, the sub-gate signs show "switch" and auxiliary switch conversion. At the same time in the opening operation, the counter 4, anti-error chain: closing operation is completed, the circuit breaker is not sub-gate, the circuit breaker will not be able to close again. Circuit breaker closing operation is completed. , If the closing signal is not removed in time, the circuit breaker internal anti-jump control loop, will cut off the closing circuit to prevent multiple reclosing. Hand car circuit breaker in the experimental position or working position, the circuit breaker can not close. Selection of latching circuit breakers in secondary control 5, the circuit breaker in line with the standard: circuit breaker in line with GB1984-2003 "indoor AC high voltage circuit breakers", IEC62271 related requirements. 1998 Chung Chung in the original. The circuit is not connected with the case, the lock solenoid will prevent manual closing. The Ministry of Machinery, the Ministry of Power Industry identification. 6, the circuit breaker features: the vacuum circuit breaker running performance is stable, breaking current, reasonable design, convenient secondary wiring, it is suitable for China's power grid operation. 7, the use of environmental conditions: : 1000m and below (at high altitude, to be specified) Ambient temperature: - 15 ℃ ~ +40 ℃ Relative humidity: Daily average ≤ 95% Monthly average ≤ 95% No dust, smoke, corrosiveness and likelihood Gas, steam, or smoke pollution and shaking vibration of the occasion, auxiliary circuit induced electromagnetic interference amplitude ≤ 1.6. 8, Technical parameters: Parameter name Unit Parameter value Rated voltage kV 12 Rated lightning impulse voltage kV 75 (phase to relative) / 85 (fracture) Rated short time Power frequency withstand voltage (1min) kV 42 (phase, relative) / 48 (Fracture) Rated frequency HZ 50 Rated short-circuit breaking current kA 25 31.5 40 Rated current A 630 1250 1250 1600 2000 2500 2000 2500 3150 4000 Rated short-time withstand current kA 25 31.5 40 Rated peak withstand current kA 63 80 100 Rated short-circuit closing current (peak) kA 63 80 100 Secondary circuit power frequency withstand voltage (1min) V 2000 Operating sequence points -0.3S- points -180 S-split points -180 S-points -180 S (40 kA is 800/400) Rated capacitor group breaking inrush current kA 12.5 (frequency not more than 10000HZ) Mechanical life times 20000 Rated short-circuit breaking current times Rated 50 times Rated Operation of the closing voltage V AC: 110/220 DC: 110/220 energy storage motor voltage V AC: 110/220 DC: 110/220 three-phase closing different period of ms ≤ 2 main circuit resistance μΩ ≤ 60 (630A ) ≤ 50 (1250A) ≤45 (1600 A) ≤ 35 (2000A) ≤ 25 (2500 or more)
