Device for uninterrupted supply of alternating current to rotating instruments

Abstract

The invention discloses a device for supplying AC power to a rotary instrument uninterruptedly. The device for supplying the AC power to the rotary instrument uninterruptedly comprises an AC power source, a metal box, a hollow insulation pipe and conducting assemblies, wherein the rotary instrument is detachably fixed inside the metal box; one end of the hollow insulation pipe is fixedly connected to one side of the metal box, and the side surface of the metal box is provided with a wire through hole; and the conducting assemblies comprises two wires, two connection bearings and two conducting copper hooks. The two connection bearings are both fixed onto the hollow insulation pipe, and the hollow insulation pipe is provided with a wire through hole; one ends of the two wires are connected with the positive electrode and the negative electrode of the rotary instrument respectively, and the other ends of the two wires are electrically connected with the two connection bearing respectively; and the bodies of the two conducting copper hooks are hooked onto the two connection bearing respectively, and the tail portions of the two conducting copper hooks are connected with the positive electrode and the negative electrode of the AC power source respectively. The device for supplying the AC power to the rotary instrument uninterruptedly achieves the uninterrupted AC current supply for the rotary instrument such as a paperless recorder and is applicable to bad environmental conditions such as high temperature, heavy fog and high moisture.

Description

technical field [0001] The invention relates to a device for continuously supplying alternating current, in particular to a device for continuously supplying alternating current to rotating instruments. Background technique [0002] The rotation of the roll products during the heating / cooling process can obtain a uniform temperature field distribution, and the acquisition of the temperature field data inside the roll body usually requires the use of a paperless recorder powered by alternating current. [0003] Taking large-scale forged steel backup rolls as an example, differential temperature heating and spray cooling are very critical processes. During differential temperature heating, the roll necks at both ends of the backup roll are supported on the supporting rollers and drive the backup rolls to rotate. During spray cooling, the backup rolls need As it rotates on the idler rollers, the paperless recorder must also rotate with it. [0004] It is a very difficult probl...

Problems solved by technology

[0004] It is a very difficult problem to provide AC power to this rotating paperless recorder. If the wire plug of the paperless recorder is directly inserted into the AC power, the wires are easy to be entangled when the support roller rotates, which is not conducive to long-term data storage. collection

If battery power is used, the power supply time is short, and it is also impossible to maintain long-term data records

[0005] Although the brush device can provide uninterrupted alternating current, on the one hand, the brush device is expensive, and the cost of using it on a paperless recorder is high; on the other hand, the ambient temperature during differential heating is very high, and the spray cooling There is also a large amount of fog and water vapor, and the brush device is not resistant to high temperature, fog and water vapor, and is prone to danger.
