Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

The first embodiment:

referring to fig. 1, in a first embodiment of the present invention, a safety device for a dry type temperature transformer includes: the fuse mounting base 1 is internally provided with a fuse; the connecting wire 2 is connected with the fuse mounting seat 1; and the switch 3 is connected with the fuse mounting seat 1 through the connecting wire 2.

The utility model provides a dry-type becomes safeties for temperature controller's theory of operation as follows:

the method ensures the protection effect of the original safety by connecting a group of contacts in parallel from two sides of a fuse mounting seat 1 in the temperature controller, leading out the contacts from the inside of the temperature controller and connecting the contacts to a switch 3 with the same capacity, and mounting the switch 3 in a junction box outside a transformer cabinet body, and when the internal safety fails, the external switch 3 can be put into use to ensure that the temperature controller continues to work normally.

the utility model provides a dry-type becomes safeties for temperature controller, before reforming transform: the transformer needs to be completely powered off when the fuse is replaced, the workload is very large, and the primary part of the transformer is out of standby after the transformer is powered off, so that the safety risk is high. After transformation, the problem can be solved only by sending the installed switch 3, thereby saving the working time and eliminating the safety risk.

Second embodiment:

based on the safety device for the dry type temperature change controller provided in the first embodiment of the present application, a second embodiment of the present application provides another safety device for the dry type temperature change controller. The second embodiment is merely a preferred way of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment alone.

The second embodiment of the present invention will be further explained with reference to the drawings and the embodiments.

Referring to fig. 2 to 5, the fuse device for a dry type variable temperature controller further includes a connecting mechanism 4 located between the connecting wire 2 and the fuse mounting seat 1, and the connecting mechanism 4 is connected to both the fuse mounting seat 1 and the connecting wire 2.
