Breaker in people's daily lives has a very important role, can play a role in protecting the circuit, then the breaker is how to play a role? How to operate the breaker correctly and safely? The following instrumentation world network of experts to tell you about the operation of the breaker in daily life and application.
The role of electrical appliances
The function of the breaker is to periodically turn on and off the primary circuit of the ignition coil, usually consisting of an electric shock and a power-off cam. Breaker contacts made of tungsten alloy deputy, a contact for the fixed contact, the other contact for the movable contact.
The fixed contact ground is realized by the fastening screw fixed on the movable bottom plate and the fixed bottom plate, and the contact gap can be adjusted by rotating the eccentric screw; the movable contact is fixed on one end of the contact arm and the other side of the contact arm One end is sheathed on the pin, the contact arm is pressed against the power-off cam by the spring piece, the contact arm is connected with the insulating post outside the shell by the spring piece and the wire. The number of lobes of the de-energized cam is the same as the number of engine cylinders. The de-energized cam is made integral with the dial and is mounted on the distributor shaft. The centrifugal weight of the centrifuge advanced mechanism is driven by the distributor shaft.
DZ47 circuit breaker that is a small circuit breaker, commonly known as air switch, is a kind of plastic shell circuit breaker. Is the construction of electrical terminal power distribution equipment cited the most widely used as a terminal protection appliances. For single-phase, three-phase short circuit, overload, overvoltage protection below 125A, including four kinds of unipolar 1P, two pole 2P, three pole 3P, four pole 4P.
DZ47 circuit breakers have excellent performance and reliable, high segmented capacity, rapid tripping and so on. DZ47 circuit breaker with its compact form factor, placed in the home pz30 distribution box , save time and effort for your home decoration. DZ47 circuit breaker housing and components made of imported high flame retardant and impact resistant plastic, energy saving, long life, for household electrical safety bring a strong guarantee!
DZ47 circuit breaker for lighting distribution system (C type) or motor power distribution system (D type), mainly used for AC 50Hz / 60Hz, unipolar 220V, two, three, four 400V, current to 60A line From overload, short circuit protection, but also under normal circumstances can not frequently switch off electrical devices and lighting lines. When the circuit current exceeds the rated current, short circuit, loss of pressure and other circumstances, DZ47 circuit breaker automatically cut off the circuit to prevent electrical fire.
The above is the simple operation and application of the breaker in daily life. It has many kinds of applications. It can be used in many occasions so that we can understand the breaker in practical application.
