Description
Technical Field
The utility model relates to a signal switching field, in particular to auxiliary switch switches structure with adjustable.
Background
GB 1985-2014 5.104.0.1 provides in summary that "the indication and the signal of the closing or opening position should not be issued unless the movable contact has reached the closing or opening position, respectively".
The position indication can be observed in situ by the indicator; the signal indication can be remotely observed through the indicator light. The signal output of most existing mechanisms provides a closing or opening signal by driving an auxiliary switch arranged in the mechanism to move.
The auxiliary switch is a part of a switch, is arranged in an operating mechanism of electric equipment such as a high-voltage or medium-voltage circuit breaker, a disconnecting switch, a grounding switch and the like, has the functions of opening and closing of a secondary circuit, signal control and interlocking protection, and can be used as a combined switch and a change-over switch. The auxiliary switch has two words of 'auxiliary' because it is not an independent one, and it is a carrier for implementing auxiliary functions of breaking, connecting and interlocking in the control system.
The F10 series auxiliary switch has the characteristics that 1, self-operated plane sliding contact is adopted, and the movable contact consists of two contact sheets; 2. the volume is small, the structure is simple, the operation is flexible, and the safety and the reliability are realized; 3. a stacked structure is used. Because the F10 series auxiliary switch adopts the laminated structure, the contact of each layer of moving contact is switched on with a certain difference; furthermore, the moving contact of the auxiliary switch of the F10 series is composed of two contact pieces, so that the moving contact is in contact with the contact piece of the static contact for a long distance to ensure the reliable connection of the contact. The moving contact contacts with the static contact at a longer distance, the signal point will be sent out in advance, which does not meet the requirements in the summary of GB 1985-2014 5.104.0.1.
To meet the requirements in the summary of GB 1985-2014 5.104.0.1, the idle stroke of the rotation of the auxiliary switch is increased, and the distance between the movable contact and the stationary contact is decreased, so that the auxiliary switch sends a signal indicating when the requirement is met. The mechanism action shaft can cause output errors due to processing, debugging and other reasons; the moving contact of the switch body also requires the rotating angle of the action shaft of the mechanism to be inconsistent due to manufacturing errors; furthermore, the F10 auxiliary switch adopts a laminated structure, the synchronism of each layer of contact is inconsistent, and the defects that the switch position signal indication is inaccurate and the interlocking between the switches and the mechanism is unreliable are caused. Therefore, it is necessary to provide an adjustable auxiliary switch switching structure to solve the above problems.
