Electric controller of integrated ring-network cabinet

Abstract

The invention discloses an electric controller of an integrated ring-network cabinet. The electric controller is an integrated sealed device. A circuit board is arranged in the electric controller and is provided with a closing control relay, an opening control relay, a rectifier bridge, an intermediate relay and an energy storage relay, and an electrical connecting and inserting piece is arranged on one side of the circuit board. The back of the circuit board is an electrical element welding foot side, and a conformal coating is brushed on the electrical element welding foot side. The front of the electric controller is provided with a closing indicating switch, an opening indicating switch, an energy storage state indicating switch, a closing and opening switching operation button and a remote and local switching operation button. A direct-current large-load circuit of the electric controller is provided with a relay playing a role in breaking, and an alternating-current relay is adopted as the relay playing the role in breaking and is provided with a plurality of breaking openings connected in series. Electric control of a switch operation mechanism of the ring-network cabinet is achieved through an integrated circuit board mode instead of traditional wiring, equipment size is reduced, and development requirements for miniaturization of outdoor ring-network cabinets can be more easily met.

Description

technical field [0001] The invention relates to an integrated ring network cabinet component, in particular to an integrated ring network cabinet electric controller. Background technique [0002] In the electric operation control of the ring network cabinet, the operating power supply is divided into two types: AC and DC. Among them, DC operating voltages are commonly used in several voltage levels such as DC24V, DC48V, DC110V, and DC220V. The load current required by the spring compression motor of the conventional high-voltage switch operating mechanism and the tripping coil can be as high as 10A. Since the direct current has no zero-crossing point, the prior art of breaking the direct current high voltage and high current can only be realized by wiring with bulky direct current contactors. With the development of outdoor ring network cabinets towards miniaturization, full insulation, and maintenance-free, the currently widely used electric operation control method that ...

AI Technical Summary

Problems solved by technology

With the development of outdoor ring network cabinets towards miniaturization, full insulation, and maintenance-free, the currently widely used electric operation control method that relies solely on secondary wiring switches can only be used for one-time equipment due to the large size of the components used and the scattered installation of components. On-site assembly, manual wiring progress is slow, error rate is high, secondary indoor components are exposed, it is difficult to achieve non-fully insulated and fully sealed, and the disadvantages of being incompatible with the environmental conditions of the outdoor place where the ring main unit operates are becoming increasingly apparent.
