Description

Technical Field

[0001] The utility model relates to the technical field of power supply protection for heat treatment furnaces, in particular to a single-stage power supply cross-power supply protection mechanism. Background Art

[0002] In order to save energy and reduce emissions, some companies will replace hot gas heat treatment furnaces with electric heat treatment furnaces. The design capacities of hot gas heat treatment furnaces and electric heat treatment furnaces are different. Electric heat treatment furnaces may be designed with higher electrical load capacity. If this is not taken into account when replacing equipment, it will easily lead to excessive electrical load. At this time, reasonable load management is needed to avoid multiple electric furnaces running at the same time to reduce the peak of the overall electrical load. However, in actual production, operators may mistakenly open multiple electric heat treatment furnaces at the same time. On the one hand, it will cause unstable power supply and affect the normal operation of equipment. On the other hand, it will increase energy consumption and increase production costs. Utility Model Content

[0003] The utility model aims to provide a single-stage power supply cross-power supply protection mechanism which can improve the stability of equipment operation and reduce production costs.

The position of the movable block can be adjusted by toggling the raised part, which is convenient for operation.

[0014] Furthermore, the sliding bottom plate is provided with a first sliding opening, the switch is located in the first sliding opening, the inner side wall of the sliding bottom plate is provided with a sliding groove, and the movable block is movably embedded in the sliding groove.

[0015] In the above scheme, the switches on the power switch box are all located within the range of the first sliding opening set on the sliding base plate, and the movable block is embedded in the sliding groove, so that the movable block can stably move along the inner wall of the sliding base plate, and also move along the path of the first sliding opening, so that the position of the movable block can be adjusted.

[0016] Furthermore, it also includes a mounting plate, wherein the mounting plate is mounted on the power switch box, and the sliding base plate is mounted on the mounting plate.

It can also protect the power switch box. The sliding bottom plate is installed on the mounting plate to ensure the stability of the sliding bottom plate.

[0018] Furthermore, the mounting plate is provided with a second sliding opening having the same size as the first sliding opening of the sliding bottom plate, and the mounting plate is made of an insulating wooden board.

[0019] In the above scheme, the mounting plate cooperates with the sliding bottom plate to process a second sliding opening of the same size as the first sliding opening on the sliding bottom plate, so that only the switch of the power switch box is exposed outside for easy operation. The mounting plate is made of an insulating wooden board to avoid

[0020] The utility model discloses a single-stage power supply cross-power supply protection mechanism, which has the beneficial effects of improving the stability of equipment operation and reducing production costs.
