Today we introduce a national invention patent for authorization - a transformer that is easy to disassemble and maintain with a contact sensor. The patent was applied by Zaozhuang Power Supply Company of State Grid Shandong Power Company and was granted an authorization announcement on November 2, 2016.
Description
The invention relates to the field of transformers, in particular to a transformer with a contact sensor which is easy to disassemble and maintain.
Background of the invention
Due to its high-voltage operating characteristics, transformers require a tight installation during use. However, when it is necessary to disassemble and maintain the main transformer execution component of the transformer (such as the body of the transformer), manual operation is required; in the case where the transformer is in a higher position, maintenance is inconvenient.
Summary of the invention
SUMMARY OF THE INVENTION It is an object of the present invention to provide a transformer with a contact sensor that is easy to disassemble and maintain, which is capable of overcoming the above drawbacks.
According to the present invention, a transformer for facilitating disassembly maintenance with a contact sensor includes a body including a core coil assembly and leads, a body base, and a mounting bracket.
The figure shows the overall structure of the transformer of the present invention.
The bottom side of the mounting bracket is for fixed connection with the transformer mounting structure, the body base is fixedly connected to the bottom of the body, and comprises at least two base strips, each of the base strips having an upper portion a protruding joint portion and a width extending portion extending below the protruding joint portion and extending outward in the width direction, the upper side of the width extending portion is covered with an upper elastic pad, and the left and right sides are covered with a side elastic pad, The lower side is provided with two rollers, and the bottom of the base strip is provided with an inverted U-shaped groove between the two rollers for the drive screw to pass through, and the upper side of the protruding joint is provided with fastening a threaded hole is configured to be engaged with the bottom of the body and fastened, and a pushing slider and a pushing slide threadedly engaged with the driving screw are respectively disposed at two sides in a longitudinal direction of each of the base strips a drive screw of each of the at least two base strips is in power and synchronous operation with a common transmission driven by a motor, and a contact sensor is disposed at a position of the right side of the drive screw adjacent to the mounting bracket, the contact Sensor and motor The connection is for transmitting a signal to control the motor to stop when the push-out slider is in contact with the contact sensor.
The top side of the mounting bracket is divided into a disassembly maintenance portion and a fastening working portion, and two sliding slots are formed through the disassembly maintenance portion and the fastening working portion, and the bottom surface of each of the sliding slots is used for The roller is engaged and the two side wall faces are vertically oriented for mating with the side elastic pads covered by the left and right sides of the width extension, and the two side wall faces are parallel to each other in the disassembly maintenance portion In the fastening working portion, they are inclined toward each other.
The top of each of the sliding grooves in the fastening working portion is fixedly connected with two fastening covers symmetrically arranged on the longitudinal axis of the sliding groove, between the two fastening covers Forming an upper channel, the side wall surface of the upper channel is divided into a trumpet-shaped guiding section for engaging with the side surface of the protruding joint to guide the pedestal strip to advance inward, and the guiding section of the side wall surface parallel to each other Engaging with a side of the raised joint to guide continued inward advancement of the base strip, wherein each of the two fastening covers includes a horizontal upper side and along a lower side that is downwardly inclined in an inwardly advancing direction of the pedestal strip for engaging an upper resilient pad covered by an upper side of the width extension, thereby being driven by the motor Pushing the slider to push the pedestal strip, and the side elastic pads covered by the left and right sides of the width extension of each pedestal strip are inclined to face each other in the fastening working portion Press-fitting of the two side wall faces and utilizing the width extension of each pedestal strip
The body and the body base are fastened on the mounting bracket, and the base strip is pushed out as the push-out slider driven by the motor drives the base strip To the disassembly maintenance portion, the body and the body base can be lifted away from the mounting frame in a vertical direction.
According to the present invention, since a mounting bracket having a maintenance portion and a fastening portion is used, it is possible to switch the body of the transformer between the two portions by power driving, thereby passing the downwardly inclined top surface in the fastening portion and The oppositely inclined side wall surface and the elastic pad at the corresponding portion fix the entire transformer body; the contact sensor is provided to transmit the signal to stop the operation of the motor when the push-out slider contacts the contact sensor, preventing the push-out from being pushed out The slider walks excessively and collides with the mounting frame. At this time, the body of the transformer is fixed in the fastening working portion; in the maintenance part, since there is no top fastening cover plate and the side wall is vertical, it can be used Lift the crane and other lifting devices.
