Temperature relay check device

Abstract

The invention discloses a temperature relay check device. The temperature relay check device comprises a check stand, first sliding rails are fixed to the inner wall of the check stand through screws,fixing plates are slidingly connected to the side walls of the first sliding rails, a heating housing is fixed to the side walls of the fixing plates through screws, an electric heating wire is woundaround the outer wall of the heating housing, a supporting table is placed on the side wall of the bottom end of the check stand, a third sliding rail is fixed to the side wall of the upper end of the supporting table through rivets, second contact plates are connected to the side walls of the two ends of the third sliding rail through studs, contact points are clamped to the side walls of the second contact plates, and springs are in threaded connection with the side walls, close to the contact points, of the second contact plates. By the arrangement of the heating housing, the electric heating wire, the first sliding rails, the fixing plates and gas bags, the temperature of liquid in the heating housing can be increased under the effect of the electric heating wire, generated gas increases the temperature in the check stand to drive the gas bags to expand, the primary work of check is completed, and smooth follow-up work of check is guranateed.

Description

technical field [0001] The invention relates to the technical field of temperature relays, in particular to a temperature relay calibration device. Background technique [0002] Temperature is an important basis for the safe operation of the main transformer under high temperature and high load conditions. In summer, the weather is hot and muggy, and it is also a period of concentrated power consumption. Most of the main transformers are operating at full load, and the winding temperature and oil temperature are close to the limit value. The displayed temperature or the node cannot be closed reliably, which will cause the main transformer to burn out, a large-scale power outage, and it is difficult to restore power supply in a short time. The serious consequences of a large amount of power loss will have a great impact on users, so the quality of the temperature relay directly affect the safe operation of the power grid.
