Abstract
An interphase overvoltage protector consists of four groups of non linear protective elements and six gas discharge tubes. All parts above are connected together in a particular way. Two groups of non linear protective elements and one gas discharge tube are connected in series to form an overvoltage protector between every two random phases; when the voltage between two random phases surpasses the discharge voltage of the gas discharge voltage tube, the discharge tube will break down and is in the short status, and the protective element will limit the voltage.
Description
The utility model relates to a kind of alternate overvoltage protection.
Along with development of electronic technology and extensive use, the problem that is caused by overvoltage is also more and more serious, as computer network be struck by lightning the back systemic breakdown, more and more the intensive integrated circuits plate since the dielectric strength difference by over-voltage breakdown, various electric equipments are damaged or the like by over-voltage breakdown, and suchlike problem has seriously influenced the use of various electronics and electric equipment.Overvoltage protection method commonly used at present is to connect lightning arrester over the ground on the protected equipment of needs; but this method can only limit overvoltage to earth; many times be the damage that alternate overvoltage has caused equipment, lightning arrester is very little to alternate superpotential restriction over the ground.
The purpose of this utility model is will provide a kind of can limit alternate superpotential overvoltage protection.
The purpose of this utility model is achieved in that with four groups of non-linear protection components and six gas discharge tubes and adopts a kind of special connection to form alternate overvoltage protection wherein all have two groups of protection components and a gas discharge tube to be composed in series overvoltage protection between the two-phase arbitrarily.
Because the utility model has been taked therefore can limit the overvoltage between any two-phase in the indirect method of protection component and gas discharge tube mutually, has reached the purpose of alternate overvoltage protection.And because the buffer action of gas discharge tube, protection component is not taken operating voltage under the normal condition, has prolonged useful life greatly, can also reduce residual voltage, improves the protection effect.
Below in conjunction with drawings and Examples the utility model is elaborated.
Figure one is a protection winding diagram of the present utility model.R1, R2, R3, R4 are four groups of non-linear protection components among the figure, and K12, K13, K14, K23, K24, K34 are six gas discharge tubes, and wherein Kij is the discharge tube that is connected between two protection components of i, j.One end of four groups of protection components is connected on system's three-phase and ground connection respectively; the other end of each group protection component is drawn three terminals; link to each other with three terminals that other three groups of protection components are drawn respectively by three gas discharge tubes, have two groups of (R2R3) protection components and a gas discharge tube (K23) to be composed in series overvoltage protection between so any two-phase (as 23).
