The invention relates to an interlocking mechanism of a jack box of a bus duct. The interlocking mechanism of the jack box of the bus duct comprises an operating handle, rotary arms, a switch strip assembly and a connecting rod assembly, wherein the rotary arms are fixed at the two ends of the switch strip assembly respectively, a U-shaped structure is formed by the rotary arms and the switch strip assembly, the bottom end of each rotary arm is connected with the connecting rod assembly through a connecting piece, the connecting rod assembly comprises a cross rod and a vertical rod, one end of the cross rod is fixed on the connecting piece, the other end of the cross rod is fixed on the vertical rod, a positioning pin is arranged on the bottom of the vertical rod, a cam assembly is arranged on the operating handle and is a hollow ring, a protruding structure is arranged on the outer side of the cam assembly, and the cam assembly is fixed on the outer side of a corresponding rotary arm through a bolt. The interlocking mechanism of the jack box of the bus duct has the advantages of being simple in structure, convenient to manufacture and install, firm in connection and fast and convenient to operate.
Description
technical field [0001] The invention relates to an accessory of power transmission equipment, in particular to a plug-in box interlocking mechanism for safely closing and opening a plug-in box and a bus duct through an operating handle on the plug-in box. Background technique [0002] As a functional unit of the power transmission bus duct, the plug box plays the role of distributing electric energy in the bus duct system. There are many ways to operate the plug-in box. After the plug-in box is inserted on the bus duct, it is very important to ensure the reliable connection between the plug-in box and the bus duct and the safe and convenient opening and closing of the switch. This will directly affect the plug-in box. Can it operate reliably for a long time. At present, the rotary switch and the operating handle are generally used to realize the power-on and power-off of the plug-in box and the bus duct, which requires connecting fixed points on the bus duct shell and the p...
