Abstract

The invention discloses an operation simple and quick inside individual loop circuit switch control cabinet of manually operated machine installation with fire control pump star bugle firing. The control cabinet includes a control cabinet body, a touch device and a convex wheel shaft clutch chest body, wherein the convex wheel shaft clutch chest body inside has convex wheel components and carrier rod components, and through a rotation handle, the control cabinet controls the convex wheel components and the carrier rod components, thereby connecting or disconnecting the touch device. The control cabinet of manually operated machine installation with fire control pump star bugle firing, through the rotation handle, carries out operations, the rotation handle when bringing along the movement of the main shaft inside the control cabinet body brings along the movements of a first convex wheel, a second convex wheel and a third convex wheel, according to a preset location of the convex wheel, the control cabinet when rotating chooses the touch device required to be connected, and is very convenient in operation and in replacing the control return circuit.

Description

technical field [0001] The invention relates to the technical field of control cabinet operation, in particular to a control cabinet with a manually operated mechanical device for star-delta start of a fire pump. Background technique [0002] When a fire incident occurs, it is necessary to start the fire pump as soon as possible to provide fire water source for fire fighting. However, when a fault occurs in the control circuit of the control cabinet for starting the fire pump, the start of the fire pump will not be completed, which often delays the fighter plane and causes losses to people's lives and property. Since relatively high-power fire pump motors are widely used in this field, and the existing fire pump control cabinets have no specific technical solutions for starting high-power fire pump motors, how to quickly start high-power fire pump motors is a urgent problems in this field. Contents of the invention [0003] In order to solve the above-mentioned technical...
