Abstract
The utility model relates to a high switching dc contactor, which is composed of a main contact arc-suppressing system and an electromagnetic system, wherein, the arc-suppressing system comprises a main contact and permanent magnetism blocks. The utility model is characterized in that the permanent magnetism blocks are arranged on both ends of arc-suppressing cover and on the same plane with the main contact; an arc separating cover is arranged outside the arc-suppressing cover; a bridge type main contact is arranged in the arc-suppressing cover; an arc separating plate is arranged between two poles of the arc-suppressing cover. Because the utility model adopts permanent magnetism arc-suppressing, a constant magnetic field can effectively solve the problems that the contact is excessively worn when a high current is switched, and arcing time is overlong when a lower current is switched; the arc separating cover is added outside the arc-suppressing cover; electric arc can be effectively elongated; thereby, the electric arc can be sprayed to the surrounding space of products; switching arc-suppressing is reliable.
Description
The utility model belongs to the low voltage electrical apparatus technology field, specifically a kind of D.C. contactor of high breaking.
D.C. contactor is to use control element more widely in electric power system, and in CD10, the CD2 of electric power system, CD5, CD6 electromagnetic operating mechanism, more generally adopt CZ0-40C, CZ0-100C D.C. contactor to finish divide-shut brake control at present, this type product is China's sixties imitative Soviet Union products, bulky, disjunction failure rate height, it is very inconvenient to use at high-voltage switch gear cabinets such as novel KYN18, KYN23, and the D.C. contactor that a kind of volume is little, breaking capacity is strong, safe and reliable is also just actively sought by the manufacturer that much produces switch cubicle.
The purpose of this utility model provides that a kind of compact conformation, body are light, the high breaking D.C. contactor of permanent magnetism arc extinguishing type.
The purpose of this utility model is achieved in that its main contact arc quenching system and vertical direct drive type electro magnetic system by upper and lower layout, main contact arc quenching system wherein includes main contact, permanent magnets, flash barrier, it is characterized in that permanent magnets be arranged on the arc-extinguish chamber two ends and with the bridge-type main contact in one plane, arc-extinguish chamber is outside equipped with the arc cover, and be provided with the bridge-type main contact in the arc-extinguish chamber, between the arc-extinguish chamber of the two poles of the earth, also be provided with flash barrier.
The utility model is owing to change traditional series connection blow-out coil arc extinguishing into permanent magnetism stationary magnetic field arc extinguishing, contact excessive wear when then constant magnetic field can solve the big electric current of disjunction effectively, a long difficult problem of arcing time during the little electric current of disjunction.This is novel because arc-extinguish chamber installs the arc cover outward additional, and electric arc is effectively elongated, and is sprayed onto the product surrounding space and be unlikely, and the disjunction arc extinguishing is reliable.This is novel also to have simple in structure, characteristics such as volume is little, (only for original product 1/4th) in light weight, cost are low, easy to maintenance, safe and reliable, long service life, applied range.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is that structural representation cuts open in office of the present utility model
Fig. 2 is the left view of Fig. 1
Fig. 3 is the vertical view of Fig. 1
Shown in Fig. 1,2,3, among the figure 8 is vertical direct drive type electro magnetic system, the top of this electromagnetic system is the main contact arc quenching system, in the main contact arc quenching system, include main contact 6, permanent magnets 4, permanent magnets 4 be arranged on arc-extinguish chamber 2 two ends and with bridge-type main contact 6 in one plane, arc-extinguish chamber 2 is outside equipped with arc cover 1, and be provided with bridge-type main contact 6 in the arc-extinguish chamber, between the arc-extinguish chamber of the two poles of the earth, also be provided with flash barrier 3.Among the figure 5 is that push rod, 7 is auxiliary contact in addition.The breaking capacity of this structure is direct current 150A, 242V, 15MS and CZ0-40C is direct current 120A, 242V, 15MS.
