Description

Operators for switchgear

technical field

The utility model relates to an operator, in particular to an operator for a switchgear, which is applied to a section switch, a grounding switch or a section-grounding composite switch of the switchgear, and is controlled by a motor or manual operation. the

Background technique

The operator for switchgear has dual functions of a segmented switch and a grounding device, which can switch the three positions of "off", "on" and "grounding", and the operation device can perform actions in three different switch positions , this system is recorded in China Taiwan Patent Case No. 91100492. the

The patent discloses that this manipulator is a motor or manual handle that turns the output shaft to switch the "off", "on" or "grounding" position of the switch. It is characterized by: a cam plate located on the output shaft , form a concave part corresponding to each position of the "off", "connect" or "ground" of the operator for the switch with the periphery of the cam plate, and formed on the surface of the cam plate, with a contact to stop the motor The pin of the micro switch, the roller for rolling the cam and the roller for locking that press on the periphery of the cam and the roller for locking, the cam follower that moves up and down by the rotation of the cam plate, and the roller for rolling the cam are on the cam In the position of "off", "on" or "grounding" of the plate, the locking roller is locked by its concave part to lock the rotation of the output shaft to hold the latch, and the concave part of the detection cam plate and the cam roll The micro switch that engages with the roller, and the lock release member that is rotated by the horizontal movement of the lock lever, disengages from the locking roller from the recess that holds the latch to release the lock, and is driven by a magnet Lock release lever. the

In the switchgear operator of the aforementioned patent, there are the following problems:

(1) The range of the stop position during electric operation is large and not fixed: the stop position depends on the concave cam plate, and the stop action is controlled by the micro switch and the electric brake of the motor. Because of the time delay characteristic of the electric brake, the locking roller Sufficient clearance must be maintained from the cam plate recess. the

(2) The stop position of manual operation is inaccurate during manual operation: the stop position of manual operation is inaccurate due to the existence of the gap between the locking roller and the concave part of the cam plate in the above (1). the

(3) Fixed torque output gain (amplification ratio): The gear box is used to transmit power, and the torque output gain is fixed, which does not meet the characteristics of the switchgear operator and requires a large torque when starting and stopping. the

(4) The solenoid actuator (solenoid) is prone to failure: since the locking roller leaves the cam plate recess and is driven by the electromagnet actuator, the electromagnet actuator needs considerable power to overcome the return force and other resistances. It is very easy to cause the coil to burn out due to improper operation or poor manufacture. the

(5) Poor use of space: the gear box used in the switchgear operator has a large space, which is not conducive to the configuration on the switchgear. the

(6) No manual anti-misoperation design: When the operator performs manual operation in the OFF (OPEN) state, it may be operated to the ON (CLOSE) or the grounding (EARTH) at will, and it does not have the design to prevent malfunctions. Because the operator turned the handle in the wrong direction, the action that should have been operated to close (CLOSE) was wrongly operated to ground (EARTH), resulting in a major accident. the

Therefore, the utility model provides an innovative new utility model that is more in line with the characteristic requirements of the switchgear aiming at the problems of the aforementioned patents. the
