Anti-theft dry-type transformer shell

Abstract

The anti-theft dry-type transformer shell comprises a shell body and two sets of side opening doors, an open area is formed in one side of the shell body, the side opening doors are symmetrically installed on the open area through lock catches, multiple sets of reinforcing assemblies are installed between the side opening doors and the open area, and anti-theft assemblies are installed on the side opening doors. A barrier plate slides in a rectangular frame to shield a second lock catch, hidden arrangement of the second lock catch is achieved, under driving of a guide spring, an extension piece is inserted into a reinforcing groove in a penetrating mode, positioning of the barrier plate is achieved, the barrier plate is prevented from moving, and the situation that the second lock catch is pried by the outside to cause theft of the transformer is avoided; the anti-theft performance of the whole shell is enhanced, and the fixing piece extends out of the positioning cavity to be inserted into the fixing groove under the cooperation of the reinforcing assembly, so that the open area and the side door are reinforced, the contact area of the open area and the side door is increased, and the strength of the side door is improved.

Description

technical field [0001] The invention relates to the related technical field of dry-type transformers, in particular to an anti-theft dry-type transformer casing. 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 and equipment, etc. The dry-type transformer is equipped with a shell for external protection, but At present, most of the keyholes of the casing are directly exposed, without hidden protection, which is very prone to malicious damage and other situations, and the security is poor. [0003] The existing technology has the following disadvantages: the strength between the existing shell and the side door is poor, and no additional reinforcement treatment is carried out, so the side door is easily peeled off from the shell under the action of external force, making the overall anti-theft effec...

[0002] Dry-type transformer refers to the transformer whose iron core and winding are not immersed in insulating oil.

[0003] The existing technology has the following disadvantages: the strength between the existing shell and the side door is poor, and no additional reinforcement treatment is carried out, so the side door is easily peeled off from the shell under the action of external force, making the overall anti-theft effect poor. At the same time, most of the keyholes of the current casing are directly exposed, without hidden protection, which is prone to malicious damage and other situations, and the security is poor, which reduces the overall anti-theft performance of the casing.
