The working principle of the old friend breaker of the terminal block

Pratt believes that the role of circuit breakers in any high-power equipment is decisive, and the terminals also provide it with excellent power-on functions. Circuit breakers can play such a big role, depending on how it works. This is true. Higher than the industrial use of the terminal.

This product's low voltage and high voltage circuit breakers work differently. The former main contact is realized by manual operation or electric closing. After the main contact is closed, the free tripping mechanism locks the main contact in the closing position. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, while the coil of the undervoltage release is connected in parallel with the supply. An important protection appliance in low voltage distribution network.

The core work of the high-voltage circuit breaker is that the arc, that is, the arc to be disconnected, can still be extinguished after being elongated. The simple point is that while the cooling arc is weakening and freeing, the arc is stretched by blowing arc to strengthen the compounding and diffusion motion of the charged particles, and the charged particles in the arc gap are blown away, so that the dielectric strength of the medium can be quickly recovered, and the Protective effects. Compared with the simple circuit protection device made of a fuse before, the advantage of the circuit breaker is that it can be used repeatedly, and it is more sensitive and safe.

The last thing I want to say is that the existence of circuit breakers is a good way to prevent accidents. Based on its powerful current protection function, Supro's terminal function is also very important. The unimpeded transmission of current and signal can guarantee the normal operation of electrical performance.
