Description

TECHNICAL FIELD

[0001] The utility model belongs to transformer protection technical field, concretely relates to a transformer temperature controller rainproof box. BACKGROUND

[0002] The transformer temperature controller is a measuring protection device for monitoring the temperature of transformer oil, and has high requirements for its protection performance in the environment such as outdoor, combined heat and power, offshore platform, etc.

[0003] The transformer temperature controller is a measuring device, and has mechanical and electrical signals for external feedback. The mechanical indication signal can be isolated from the outside, and is observed through the sealed transparent inspection window. The electrical indication signal has a terminal board in the terminal box, and needs to be connected to the terminal board of the terminal box through the wire of the contact of the electrical element in the meter. The dial plate and the internal body of the conventional temperature controller are not completely sealed, and the following problems may occur in the actual use process:

[0004] 1) The dial plate of the temperature controller will be aged after long-term sun exposure, and the dial plate will be blurred to cause observation problems;

[0005] 2) The internal terminal of the temperature controller is easily invaded by moisture and rainwater along the dial plate or the cover, which causes the moisture in the dial plate to easily cause the electrical element in the meter to be damp, the metal parts to be corroded, the internal contact of the temperature controller to be poor, the temperature controller to be misoperated, and the equipment to be damaged, etc.

[0006] 3) The sealing between the temperature controller probe and the oil tank temperature measuring seat may be aged and infiltrated after long-term operation.

[0007] The temperature controller rain cover for transformer of Chinese patent CN202940093U also has a temperature controller meter rain cover and a temperature controller sensor rain cover, but the rain cover is a semi-closed structure. Although this design can reduce the direct erosion of rainwater on the temperature controller to a certain extent, it cannot completely block the infiltration of rainwater. Especially in harsh weather conditions for a long time, rainwater may enter the inside through the gap or the incompletely closed part of the rain cover, causing damage to the temperature controller. SUMMARY

[0008] The utility model discloses a transformer temperature controller rainproof box, which can effectively block the entry of rainwater, protect the internal electronic elements of the temperature controller from being affected by moisture, and facilitate daily inspection and maintenance.

[0009] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0010] The utility model provides a transformer temperature controller rainproof box, which comprises a temperature controller body rainproof box and a temperature controller probe rainproof box.

[0011] The temperature controller body rainproof box is provided as a fully-closed structure, a first transparent window is movably connected to the temperature controller body rainproof box, a plurality of wire outlets are arranged below the box body of the temperature controller body rainproof box and the first transparent window, a plurality of fixing members are arranged inside the temperature controller body rainproof box, and a transformer is arranged on the fixing members;

[0012] The temperature controller probe rainproof box is mounted on the top of the transformer oil tank, a second transparent window is arranged on the temperature controller probe rainproof box, and the temperature controller probe rainproof box is provided as an open cover structure.

[0013] The first transparent window and the second transparent window are both stainless steel transparent windows or tempered glass transparent windows.

[0014] The temperature controller probe rainproof box is provided with two wire outlets on one side.

[0015] A sealing strip is arranged between the temperature controller probe rainproof box and the top of the transformer oil tank.

[0016] The wire outlets of the temperature controller body rainproof box are provided with waterproof joints.

[0017] A door lock is arranged on the temperature controller body rainproof box and the first transparent window.

[0018] The second transparent window is fixedly connected to the temperature controller probe rainproof box through screws or pressing strips.

[0019] Welding fixing pieces are arranged on the outside bottom of the temperature controller probe rainproof box, the number of the welding fixing pieces is two, and the two welding fixing pieces are coincident with the positions of the threaded seats of the top of the oil tank.

[0020] The temperature controller probe rainproof box is fixed in the threaded seats of the top of the oil tank through bolts and the welding fixing pieces.

[0021] Compared with the prior art, the temperature controller has the following beneficial effects:

[0022] This utility model provides a rainproof enclosure for a transformer temperature controller. By adopting a fully enclosed structure, the rainproof enclosure for the temperature controller body effectively prevents rainwater from entering, protecting the internal electronic components from moisture and preventing problems such as short circuits and corrosion caused by rainwater. The rainproof enclosure for the temperature controller probe is designed as an open cover structure. This structure allows the temperature controller probe to be more easily installed on top of the transformer tank and facilitates future maintenance and replacement, ensuring that the temperature controller probe can accurately measure the temperature of the transformer tank without interference from rainwater. In addition, the rainproof enclosures for the temperature controller body and the temperature controller probe are respectively provided with a first transparent window and a second transparent window, allowing maintenance personnel to directly observe the display status of the temperature controller and the installation status of the probe without opening the rainproof enclosure, facilitating daily inspections and troubleshooting.
