摘要： Provided are a switch (200), a contact protection assembly (100) for a switch (200) and a manufacturing method thereof. The contact protection assembly (100) comprises a protection cover assembly (101) rotatably coupled to a moveable blade (201) of the switch (200), the moveable blade (201) being rotatable about a first shaft (203) of the switch (200) to change an engagement status of contact fingers (2011) of the moveable blade (201) with a fixed contact (202); a second shaft (103) arranged at a distance from the first shaft (203); and an actuation rod (102) coupled between the protection cover assembly (101) and the second shaft (103) and configured to be rotatable about the second shaft (103) with a rotation of the moveable blade (201), wherein the second shaft (103) is arranged parallel to the first shaft (203) to enable the actuation rod (102) to push or pull the protection cover assembly (101) to rotate between a covering position and an exposing position, wherein the protection cover assembly (101) covers the contact fingers (2011) at the covering position and exposes the contact fingers (2011) at the exposing position. With the contact protection assembly (100), foreign objects like ice covering the contact fingers (2011) can be easily removed with the rotation of the protection cover assembly (101). This arrangement makes the switch (200) such as an earthing switch meet requirements of relevant standards, which require that the engagement of contact fingers (2011) with the fixed contact (202) cannot be affected in a case where the contact fingers (2011) are covered by a 20mm ice layer. In this way, the stability of the switch (200) is improved.

摘要： A balance spring assembly for a disconnector(200). The balance spring assembly comprises a push rod (101)partially and coaxially arranged in a blade (201)of the disconnector(200) which is rotatable about a first shaft(103) to change an operation status of the disconnector(200), a first end of the push rod(101) fixed to a second shaft(202) so that the push rod (101)is rotatable about the second shaft(202); and a spring(102) arranged in the blade (201)and around the push rod(101), the spring(102) held between a second end of the push rod(101)and an end of the blade (201)adjacent to the first shaft(103), wherein the second shaft(202) is arranged parallel to the first shaft (103)to enable the push rod(101)to axially move in the blade(201) with a rotation of the blade(201) to thereby compress or decompress the spring(102). By arranging the balance spring assembly at least in part in the blade(201) of the disconnector(200), only one set of the spring(102) is needed. Furthermore, extra components such as the protective tube, the auxiliary spring and some connection elements are no longer needed. In this way, the manufacturing and assembling costs are significantly reduced. Furthermore, with this arrangement, the spring(102) can fully work during the whole process when the blade(201) is rotated from the open position to the close position.
