摘要： An arc path formation unit and a direct current relay are disclosed. The arc path formation unit, according to various embodiments of the present invention, includes a Halbach array provided in at least one of the forward and backward directions. The Halbach array forms a magnetic field within an arc chamber by itself or along with another magnetic body. An electromagnetic force may be generated for inducing an arc that is generated by a formed magnetic field and current flowing through the direct current relay. The electromagnetic force is generated in a direction away from each fixed contact. Accordingly, the generated arc can be extinguished and discharged effectively.

摘要： A relay (100) includes: a cavity (11) is defined in a housing (1). A number of stationary contacts (12) are arranged on the housing (1) at intervals and at least partially arranged in the cavity (11). A drive shaft (2) is movable relative to the housing (1) in an axial direction of the drive shaft (2), and an axial end is provided with a support piece (21) at least partially inserted into the cavity (11). A moving contact assembly (3) is matched with the support piece (21) through a sliding structure, so that the moving contact assembly (3) is movable relative to the support piece (21) between a first position contacting the stationary contact (12) and a second position away from the stationary contact (12). An elastic member (5) is arranged between the moving contact assembly (3) and the support piece (21) to apply an elastic force to the moving contact assembly (3) to move toward the first position.

摘要： An arc path formation unit and a direct current relay comprising same are disclosed. An arc path formation unit according to an embodiment of the present invention comprises a plurality of magnet parts. The plurality of magnet parts can form a magnetic field in a space inside an arc chamber to form an electromagnetic force for moving generated arc. The magnetic field formed by each magnet part forms an electromagnetic force toward the outside of the arc chamber. Electromagnetic forces formed adjacently to fixed contacts are formed in opposite directions. Therefore, the generated arc can be quickly moved to the outside and extinguished without damage to each constituent element of a direct current relay caused by the generated arc.

摘要： A switching appliance comprises a first housing and a second housing installed on one side of the first housing and used to accommodate an auxiliary contact mechanism, wherein the first housing comprises a lower housing, and an upper housing used to accommodate a main contact mechanism; the auxiliary contact mechanism comprises a linkage member connected to the main contact mechanism; a mounting leg that extends to the side surface of the side wall of the lower housing is arranged at the bottom of the second housing; a first clamping groove is formed in the side surface, facing the lower housing, of the mounting leg, and a second clamping groove which is opposite to the first clamping groove is formed in the side wall of the lower housing; the mounting leg is connected to the side wall of the lower housing through a connector; and the connector is simultaneously inserted into the first clamping groove and the second clamping groove in a direction perpendicular to the linkage member to fix the second housing and the first housing. According to the switching appliance, the assembling directions of the linkage member and the connector are set to perpendicular to each other, without any interference during assembly. Therefore, the switching appliance has the characteristics of convenience in assembly and simple structure.

摘要： Electrical switching devices that can have a housing cup 104 having an opening and a header 102 covering and making a seal with said cup. Internal components are included within the housing, with the internal components configured to change the state of the switching device from a closed state and an open state in response to input. The closed state allows current flow through said device and the open state interrupts current flow through said device. A plurality of fixed contacts 106a, 106b are included that are electrically connected to said internal components for connection to external circuitry, wherein the the fixed contact pass though the header 102 with a portion exposed above the header. A plurality of glass/ceramic eyelets 120 are included, each of which is mounted to a respective one of the fixed contacts 106a, 106b on the exposed portion of its one of the fixed contacts. Each of the eyelets 120 can be radially symmetric about its one of the fixed contacts, with the eyelets covering less than all of the header.

摘要： A power supply assembly comprising an alternating current primary source connection (41), a secondary source connection (42), a load connection (71), a primary current supply route (457), a supply switch system (5), and a converter system (8). The primary current supply route (457) electrically conductively connects the primary source connection (41) to the load connection (71). The supply switch system (5) is adapted for disconnecting the primary source connection (41) from the load connection (71). The converter system (8) is adapted for supplying power from the secondary source connection (42) to the load connection (71) during a first converter supply mode. The supply switch system (5) comprises a mechanical circuit breaker (51) whose opening time is short, and in a first supply transition operation, power transmission is transferred from the mechanical circuit breaker (51) directly to the converter system (8).
