Description
Technical Field
The utility model relates to an intelligence medium voltage circuit breaker technical field.
Background
The conventional medium voltage circuit breaker has the following problems:
1. the problem of the internal portion of the cabinet can only be monitored, and the problem of the brake body cannot be detected. In the long-term operation process of important equipment such as a high-voltage switch cabinet, a bus joint and the like, the contact and bus connection parts of a circuit breaker/isolating switch generate heat due to aging or overlarge contact resistance, and if the temperature of the heating parts cannot be monitored in real time, fire and large-area power failure accidents can be caused finally. For a long time, the temperature of the visually visible area was measured periodically by using a thermal infrared measuring tool, but it was difficult for the maintenance personnel to monitor the temperature value of the circuit breaker and switch cabinet link. The installation of common thermocouples, optical fibers and binding type temperature sensors influences the heat dissipation and electromagnetic field structure of the circuit breaker, and insulation accidents of the switch cabinet are easily induced. That is, there is room for improvement in temperature monitoring.
2. The handcart type circuit breaker brings great convenience for overhauling, maintenance and the like, but temperature rise and insulation accidents caused by incomplete operation of the handcart position of the circuit breaker often happen. How to avoid the problems is one of the main difficulties in the cabinet matching monitoring of the circuit breaker and the switch cabinet. At present, the common method is to install an auxiliary switch and a position switch on a circuit breaker handcart and monitor the position of the handcart through the auxiliary switch. The scheme is simple and effective, but in actual operation, because the precision of the position switch is limited, the auxiliary switch is already actuated when the handcart approaches the position in many times. In addition, since the position switch is arranged at the bottom of the handcart, when the top of the circuit breaker is inclined, the actual state cannot be read from the auxiliary switch. In brief, the position switch determines the position of the breaker according to the position of the chassis, and cannot determine abnormal conditions such as the inclination of the breaker.
