Let's share this video with you about the 50-fold slowdown:
BreakerIt can be used to allocate electrical power, to activate the arcade motor less frequently, and to protect power lines and motors. When they have severe overload or short circuits and failure of pressure, they can automatically cut circuits, which are functionally equivalent to a combination of a molten switch and an unheated relay, etc. Also, spare parts are generally not required after the breakdown of the malfunctioning current. Currently, a wide range of applications are available。
The circuit breakers typically consist of a contact system, an arc system, an operator, a button, a shell, etc. The circuit breakers are divided into high-pressure breakers and low-pressure breakers according to their range of use, and the high-pressure line is more vaguely defined and generally referred to as high-pressure appliances above 3 kv。
When short circuits are short, the magnetic field generated by large currents (usually 10 to 12 times) overcomes the reflex spring, the detachor pulls the operational action, and the switch jumps at once. When overloading, the current becomes larger, the heat is increased, and the double-metal plate is deformed to a certain degree to drive the institutional action (the larger the current, the shorter the action time)。
Today we're talking about this through a 3d animation, and have you ever wondered why some switches are different from other switches, and why we have a box with switches:
The role of breakers is to cut off and connect load circuits, as well as to cut down fault circuits, prevent accidents and ensure safe operation。
Low-pressure breakers, also known as automatic air switches, can be used to connect and break load circuits, as well as to control electric motors that are not activated frequently. Its functions are the sum of some or all of the functions of a switch, a current relay, a loss of pressure relay, a heat relay and a leak protection, and an important protective electrical device in a low-pressure distribution grid。
The primary contact point of the low pressure breaker is manual or electric. When the main point of contact is closed, the free-deductive body locks the main point of contact to the gate position. The thermal elements of the trough and the thermal desalver are linked to the main circuit, and the wiring and power supply of the compressor are due。
When the circuit is short-circuited or severely overloaded, the artery of the pass-through deductor binds the free-deductive institutional action and the main contact point breaks the main circuit. When the circuit passes, thermal elements of the heat deductor heat up the double-metal plate, which promotes free deductive institutional action. When the circuits are under the voltage, the title iron of the deductor is released. It is also a free-deductive action. Deductors are used as long-range controls, and at normal working hours, the wires are out of charge, and when distance control is required, press the start button to make the wires electrified。
