Electrical appliances for ships. With the increasing degree of ship electrification and automation, the power of ship power station is increasing, and the role of marine power distribution equipment (such as various fuses and circuit breakers) is becoming more and more important. In addition,
various marine power equipment, such as steering gear, windlass, winch and winch, etc., have complex working conditions and large load changes, so the marine control appliances used in the electric drive of the ship (such as All kinds of contactors, relays, controllers, master electrical appliances,
resistors and rheostats, etc.) also have higher requirements.
用于船舶上的動(dòng)觸頭與在左邊的靜觸頭閉合后接通電路。當繼電器受到強烈沖擊時(shí),兩鋼球吸收沖擊能量,產(chǎn)生向中間運動(dòng)的力,并推動(dòng)跳子沿箭頭A方向運動(dòng),其下端壓住觸頭,限制了動(dòng)觸頭的彈跳運動(dòng)或跳離靜觸頭的誤動(dòng)作,從而保證觸頭系統在受沖擊的情況下可靠地工作。
It is used to connect the circuit after the moving contact on the ship is closed with the static contact on the left. When the relay is subjected to strong impact, the two steel balls absorb the impact energy and generate a force to move towards the middle, and push the jumper to move along the direction
of arrow a. the lower end of the ball presses the contact, which limits the bounce movement of the moving contact or the misoperation of the jumping away from the static contact, so as to ensure the reliable operation of the contact system under the impact.
