Transfer switching equipment

A transfer switching equipment, comprising:

• a first switch set for connecting a first power supply to a load, comprising a neutral pole and at least one phase pole, wherein the neutral pole and each of said at least one phase pole of the first switch set respectively comprise a movable contact and a stationary contact, and the neutral pole of the first switch set comprises a first locking mechanism and a first linkage member;
• a second switch set for connecting a second power supply to the load, comprising a neutral pole and at least one phase pole, wherein the neutral pole and each of said at least one phase pole of the second switch set respectively comprise a movable contact and a stationary contact, and the neutral pole of the second switch set comprises a second locking mechanism and a second linkage member;
• and
• characterized in that the transfer switching equipment is configured in a way that with aid of the first locking mechanism, the second locking mechanism, the first linkage member and the second linkage member, during the switching from a closed state of one of the first switch set and the second switch set to a closed state of the other of the first switch set and the second switch set, there is a state in which the neutral pole of the first switch set and the neutral pole of the second switch set are closed at the same time while all phase poles of the first switch set and all phase poles of the second switch set are all opened;
• further comprising a first drive mechanism and a second drive mechanism, wherein the first drive mechanism comprises a first drive shaft, and the second drive mechanism comprises a second drive shaft;
• wherein, the first locking mechanism comprises:
• a first link rotatably arranged on the first drive shaft, and a first U-shaped link hinged between the first link and the movable contact of the neutral pole of the first switch set;
• the second locking mechanism comprises:
• a second link rotatably arranged on the second drive shaft, and a second U-shaped link hinged between the second link and the movable contact of the neutral pole of the second switch set.
