Embodiment 1

[0042] Embodiment 1 includes an isolation box 1 and a fixed frame 6, an air intake pipe 101 is installed through the bottom wall of the isolation box 1, a dehumidification filter screen 102 is installed on the inside of the air intake pipe 101, and a suction pipe 101 is installed at the bottom of the air intake pipe 101. Fan 103, air outlet pipe 104 is installed through the bottom wall of isolation box 1, blower 105 is installed at the bottom of outlet pipe 104, the front of isolation box 1 is connected with door body 106 by hinge, suction fan 103 at the bottom of air intake pipe 101 In operation, the outside air is sucked into the inside of the intake pipe 101, and the movement of the air is guided by the intake pipe 1. During the process of air movement, the moisture in the air is filtered by the dehumidification filter 102 to prevent moisture from entering the device. The air intake pipe 101 transmits the dry air to the inside of the isolation box 1, while the blower 105 is ...

Embodiment 2

[0044] Embodiment 2 includes an isolation box 1 and a fixed frame 6. A fixing seat 202 is installed on the inner bottom wall of the isolation box 1 through bolts. The top of the fixing seat 202 is equipped with a lower splint 201 through bolts, and the fixing seat 202 is fixed At the bottom of the isolation box 1, the stability of the device is ensured, and the fixing seat 202 is convenient for fixing the lower splint 201 on the top. The top of the lower splint 201 is equipped with a transformer main body 2 through a spacer, and a high-voltage connection is installed on the front of the transformer main body 2. Two groups of connectors 204 are installed on the front of the transformer body 2, and the two groups of connectors 204 are located above and below the high-voltage connector 203. The front end of the connector 204 is threaded with an assembly cover 205, and the top of the transformer body 2 and A fixed yoke 206 is installed at the bottom, and two sets of upper extrusion...

Embodiment 3

[0046] The third embodiment includes an isolation box 1 and a fixed frame 6. The inner walls of the isolation box 1 on both sides are equipped with a fixed shell 3 through bolts, and a ventilation hole 301 is opened on one side of the outer wall of the fixed shell 3. The fixed shell 3 Moisture-proof agent 302 is installed on the inner side of the box, and the fixed shell 3 is fixed by the isolation box 1 to ensure the stability of the fixed shell 3. The air hole 301 on the fixed shell 3 transmits air, and the moisture-proof agent 302 inside the fixed shell 3 Absorb moisture in the air, thereby reducing the humidity inside the isolation box 1. Since the moisture-proof agent 302 is embedded in the fixed shell 3, workers can easily take the moisture-proof agent 302 out of the fixed shell 3 to complete the moisture-proof agent 302. The replacement is convenient for workers to operate. Temperature and humidity indicators 4 are installed on the outer walls of both sides of the isolat...

Abstract

The invention discloses an intelligent temperature control type three-phase resin insulation dry-type transformer which comprises an isolation box and a fixing frame. A fixing base is installed on the bottom wall of the inner side of the isolation box through bolts, a lower clamping plate is installed at the top of the fixing base through bolts, and a transformer body is installed at the top of the lower clamping plate through a cushion block; and fixing shells are installed on the inner walls of the two sides of the isolation box through bolts, temperature and humidity displays are installed on the outer walls of the two sides of the isolation box, and a wire arranging pipe is installed on the inner wall of one side of the isolation box in a penetrating mode. According to the invention, the fixing shells are installed, air is conveyed through the vent holes in the fixing shells, moisture in the air is absorbed by a moisture-proof agent in the fixing shells, and therefore the humidity in the isolation box is reduced, and due to the fact that the moisture-proof agent is embedded in the fixing shells, a worker can easily take out the moisture-proof agent from the interior of each fixing shell to complete replacement of the moisture-proof agent; and worker operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to an intelligent temperature-control type three-phase resin-insulated dry-type transformer. Background technique [0002] Dry-type transformer refers to the transformer whose iron core and winding are not immersed in insulating oil. It is widely used in local lighting, high-rise buildings, airports, wharf CNC machinery equipment, etc. Three-phase dry-type transformer is the main component of various power supplies and electrical equipment. It is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coil, secondary coil and iron core. [0003] The disadvantages of dry-type transformers in the prior art are: [0004] 1. Patent document CN212032819U discloses a dry-type transformer that is convenient for dust removal, "It includes a dry-type transformer box, a dry-type transformer body, an exhaust fan, a ...
