Abstract

This invention belongs to the field of circuit breaker technology and discloses a high-voltage circuit breaker matching and testing device and method for measuring friction force. The device includes a drive source, a linear motion mechanism, a displacement measuring component, a friction force measuring component, and a control terminal. The drive source drives the linear motion mechanism to move vertically. One end of the sealing rod near the pin hole is connected to the output end of the linear motion mechanism, which positions the sealing rod in the installation position so that the pin hole and the connecting hole can be connected via a mounting plate. The displacement measuring component measures the displacement of the sealing rod. The friction force measuring component measures the friction force of the circuit breaker body in real time. The control terminal is signal-connected to both the displacement measuring component and the friction force measuring component, and electrically connected to the moving arc contact and stationary arc contact of the circuit breaker body. The control terminal can set the stroke, contact stroke, parasitic stroke, and friction force limit value. This invention achieves high automation, high accuracy, low cost, and high efficiency in matching and testing and friction force measurement.
