Abstract

FIELD: electrical engineering. SUBSTANCE: circuit bleaker has vacuum arc chute 1 with movable contact 2 and fixed contact 3, double-arm lever 4 coupled with movable contact, dashpot 5, roller 6 mounted on lever, bush 7 carrying hold-down spring 8 and disconnecting spring 9 both mounted with one end on common bush joined with drive rod and is free to move over it on guide cleat 10; bush 7 is locked in OFF-position by pin 11. Other end of bush compression spring is fixed on drive rod and that of disconnecting spring, on rigid base; device for damping energy of moving parts is mounted on moving base and is engageable with roller; drive rod takes stretching force only. EFFECT: simplified design.

Изобретение относится к области электротехники, в частности к высоковольтным выключателям. Выключатель содержит вакуумную дугогасительную камеру 1 с подвижным 2 и неподвижным 3 контактами, двуплечий рычаг 4, буферное устройство 5, ролик 6, втулку 7, на которой установлены пружина поджатия 8 и пружина отключения 9, причем втулка имеет возможность перемещаться по направляющей планке 10 и фиксируется в крайнем отключенном положении штифтом 11. Использование изобретения позволяет упростить конструкцию выключателя за счет того, что пружина отклонения и пружина поджатия установлены одним концом на общую втулку, которая связана с приводным штоком и имеет возможность перемещаться по нему и во действует на двуплечий рычаг, связанный с подвижным контактом, другим концом пружина поджатия жестко закреплена на приводном штоке, пружина отключения - на жестком основании, а устройство гашения энергии подвижных частей размещено на неподвижном основании и взаимодействует с роликом, установленном на рычаге, при этом приводной шток воспринимает только растягивающее усилие.The invention relates to the field of electrical engineering, in particular to high-voltage circuit breakers. The switch comprises a vacuum arcing chamber 1 with movable 2 and fixed 3 contacts, a two-arm lever 4, a buffer device 5, a roller 6, a sleeve 7 on which a preload spring 8 and a trip spring 9 are installed, the sleeve being able to move along the guide plate 10 and is fixed in the extreme disconnected position by the pin 11. Using the invention allows to simplify the design of the switch due to the fact that the deviation spring and the preload spring are installed at one end on a common sleeve that is connected to the drive m by the rod and has the ability to move along it and acts on the two-arm lever connected with the movable contact, the other end the preload spring is rigidly fixed to the drive rod, the disconnect spring is on a rigid base, and the energy suppressor of the moving parts is placed on a fixed base and interacts with the roller mounted on the lever, while the drive rod receives only tensile force.
