Bridge cable protection device for municipal bridge engineering

Abstract

The invention discloses a bridge cable protection device for municipal bridge engineering, and the structure thereof comprises an overload protection and manual disconnection device, a left opening and closing door, handles, a right opening and closing door, fixed through holes, a fixed bottom plate, a cable line, a projection, a control panel, venting slots, a suspension ring ear, a voltmeter andan ammeter. The suspension ring ear is attached to the center of the upper surface of the overload protection and manual disconnection device, the ammeter is in glued connection with the upper left end of the front surface of the overload protection and manual disconnection device, the voltmeter is attached to the right side of the ammeter, and the voltmeter and the ammeter are on the same horizontal plane. The bridge cable protection device is provided with the overload protection and manual disconnection device, when the instantaneous value of the voltage or current passing through the cable exceeds the tolerance range of the cable, the device automatically disconnects the circuit to prevent the cable from being burned out, and when the cable line needs to be repaired, the branch of thecable line can be manually powered off, which is convenient to use.

Description

technical field [0001] The invention relates to a bridge cable protection device used in municipal bridge engineering, belonging to the field of cable protection. Background technique [0002] Cable protection is mainly divided into two categories, one is impact and rolling or high temperature from the outside, which will damage the cable, and the second is when the cable is repaired, the cable is segmented and the circuit of the cable needs to be disconnected , a protective device is needed at this time. [0003] The equipment in the prior art cannot protect the cable well when the instantaneous value of the voltage or current transmitted by the cable is too large. The voltage or current may exceed the withstand range of the cable, causing the cable to be damaged or even affecting the normal operation of the power supply line. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a bridge cable...
