Problems solved by technology

[0002] A power transformer is a static electrical device that is used to convert a certain value of AC voltage (current) into another or several voltages (current) with the same frequency. The protection of equipment and transformers is particularly important, but some substations located in low-lying areas often have the risk of transformers being soaked due to excessive water accumulation in the face of heavy rain or flood weather, resulting in equipment damage. Devices that can isolate transformers based on water level are particularly important

Abstract

The invention discloses a device for isolating a transformer according to a water level. The device comprises a machine body, a first sliding cavity with an upward opening is formed in the upper end face of the machine body, and a lifting isolation mechanism is arranged in the first sliding cavity; the lifting isolation mechanism comprises first compression springs fixedly connected to the inner walls of the left side and the right side of the first sliding cavity in a bilateral symmetry mode, and a first sliding block slidably connected into the first sliding cavity is fixedly arranged at theother end of each first compression spring. Contact sensors are controlled to work by means of water accumulation amount, and then the effect of transformer isolation by lifting an isolation placingplatform under the cooperation of a motor, when accumulated water continuously rises, an isolation cover is put down through the cooperation of the motor and an isolation control rod, the effect of completely isolating the transformer from the outer side of the device is achieved, and when the accumulated water disappears, the motor is controlled to rotate reversely through a distance sensor, andthe device reset effect is achieved.

Description

technical field [0001] The invention relates to the field related to substations, in particular to a device for isolating transformers according to water levels. Background technique [0002] A power transformer is a static electrical device that is used to change a certain value of AC voltage (current) into another or several voltages (current) with the same frequency, as a common power in a substation. The protection of equipment and transformers is particularly important, but some substations located in low-lying areas often have the risk of transformers being soaked due to excessive water accumulation in the face of heavy rain or flood weather, resulting in equipment damage. Because of the invention of a Devices that provide transformer isolation based on water level are particularly important. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for isolating the transformer according to the water level...
