Automatic transfer switching device with manual/automatic transfer device

Abstract

An automatic transfer switching device with a manual / automatic transfer device comprises a bottom plate, a motor, two breakers, two release catches, a mandrel, a controller, a casing and the manual / automatic transfer device. The manual / automatic transfer device is formed by two guide rails, a manual / automatic indicating member, a padlock indicating member, a spring and a micro-switch. The automatic transfer switching device with the manual / automatic transfer device enables all components of the manual / automatic transfer device to be arranged together intensively, and therefore structural design is reasonable and compact, and occupied space is small. In addition, when observation is performed from the outside, states of the components are very obvious and visual. In addition, the automatic transfer switching device with the manual / automatic transfer device has the advantages of being convenient to operate, low in cost and the like.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an automatic switch electrical appliance with a manual / automatic switching device. Background technique [0002] The automatic transfer switch appliance is a widely used terminal appliance. It mainly uses the controller on it to drive the electric operating mechanism to control the action of the switch, so as to connect or disconnect the common and standby power sources, so as to ensure the safety of the power system and the production efficiency. continuity. figure 1 It is a schematic diagram of the main components of a commonly used automatic transfer switch electrical appliance. like figure 1 As shown, this automatic transfer switch appliance mainly includes a base plate 1, a motor 2, two circuit breakers 3, two escapements 4, a mandrel 8, a controller and a casing not shown in the figure; wherein the motor 2 is installed on the base plate 1; two ci...

AI Technical Summary

Problems solved by technology

But, there is following problem in this prior art automatic transfer switch electric appliance: also be installed on the shell of this automatic transfer switch electric appliance manual / automatic changeover device, thereby make it have manual and electric two kinds of functions, when needs use manual function At this time, the operator needs to use the manual / automatic conversion device to convert the automatic transfer switch from the automatic mode to the manual mode, and then insert one end of the handle not shown in the figure into the shaft hole 5 on the mandrel 8, and then manually Turn the handle and the arbor 8 to rotate the escapement 4, thereby switching the circuit breaker 3

However, the components on the currently commonly used manual / automatic conversion device are set separately, so it is inconvenient to operate, takes up a large space, and the display status is not intuitive, which will undoubtedly affect the quality of the product
