Isolation switch conductive portion bent at right angles from a static contact the copper plate, which has a hole at one end can be connected by screws to the bus; the other end of the shorter (Part 1 Weihai pressure isolation switch, 2), closing it and moving blade (movable contact) is contacted. Composition of two copper contact strip (part 3), also known as the movable contact, pivotally certain angle, when it is clamped closing the stationary contact. There clamp spring (part 4) for adjusting the contact pressure between the fixed and moving contacts between the two copper plates, copper plates at the same time both in the current flowing in the same direction, produces an electromotive force of attraction between them, which increases the contact pressure of the high-pressure isolation switch, improved operational reliability. When the contact strip is mounted at both ends of galvanized steel (Part 6) is called a magnetic lock, which ensures that the fault current flowing through the short circuit, the mutual attraction force generated magnetic locking magnetized to enhance the contact pressure of the contact, thereby increasing the dynamic and thermal stability of the isolation switch. Power plants and high-voltage isolation switch is important substation electrical system electrical switches, need and supporting the use of high voltage circuit breakers, its main functions are: to ensure that high-voltage electrical equipment at the time of repair work and security Qingdao high-voltage isolation switch, play the role of isolation voltage can not be used and cut into breaking load current and short-circuit current, can be used not only to produce some powerful arc switching operation, that it does not have the interrupter function; according to the installation site is divided into different, inside and outside type style Suqian pressure isolation switch, divided by the number of insulating pillars, single-pole, double-column and three-column, the voltage level has optional equipment. Suqian pressure isolation switch, high voltage isolation switch, the power provided by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
