Module replacement device of high voltage direct current transmission system
Provided is a module replacement device of a high voltage direct current transmission system. In the device, a replacement base is provided in a structure by using a support member such that a sub-module movably provided at a fixing base of the structure can be replaced by being withdrawn outside of the structure. Further, the replacement base can easily and firmly be provided in the structure such that the module can be replaced in an easy and safe manner.
1. A module replacement device of a high voltage direct current transmission system, wherein a module is replaced by being withdrawn outside a structure of the high voltage direct current transmission system in a state where the module replacement device is provided in the structure of the system, the module replacement device comprising:
a replacement base provided such that a rear end thereof is seated in an insulation support part of the structure for electrically insulating between the structure and the module and a front end thereof extends in a forward direction of the structure such that the module is seated therein after being withdrawn; and
a support member connected to the front end of the replacement base at a first end thereof and connected to the structure at a second end thereof so as to support the replacement base to be horizontal,
wherein the rear end of the replacement base is hooked to the insulation support part of the structure so as to be prevented from moving in forward and inward directions of the structure.
2. The module replacement device of claim 1 , wherein the replacement base includes:
a base plate formed with side walls at opposite sides in a width direction thereof;
a connection guide part provided at each of opposite sides of a rear end of the base plate such that a fixing base provided in the structure is guided to an inside of the base plate; and
a guide rail provided at each of the opposite sides in the width direction of the base plate by extending in parallel to each other so as to guide movement of the module.
3. The module replacement device of claim 2 , wherein
a first hook is provided at the rear end of the base plate by being supported by the insulation support part, so as to prevent the replacement base from moving to an inside of the structure; and
a second hook is provided at a rear end of a guide bottom surface forming the connection guide part by being supported by the insulation support part, so as to prevent the replacement base from moving outside the structure.
4. The module replacement device of claim 3 , wherein the base plate defining a rear end of the guide rail is provided with a rail connection guide having a rail slot so as to guide a fixing rail of the fixing base provided in the structure to be matched with the guide rail.
5. The module replacement device of claim 4 , wherein the rail connection guide includes:
the guide bottom surface provided by extending from the base plate; and
a guide side wall provided by bending from the guide bottom surface and by extending from one of the side walls formed on the base plate, wherein
the guide side wall is provided with an enlarged part that extends inclinedly from one of the side walls.
6. The module replacement device of claim 1 , wherein the support member comprises:
a wire provided with a connecting ring at at least one of opposite ends of the wire, with a turn buckle provided at an end of the wire such that the replacement base is horizontally mounted.
7. The module replacement device of claim 6 , wherein the replacement base further includes a level.
8. The module replacement device of claim 2 , wherein the support member comprises:
a wire provided with a connecting ring at at least one of opposite ends of the wire, with a turn buckle provided at an end of the wire such that the replacement base is horizontally mounted.
9. The module replacement device of claim 3 , wherein the support member comprises:
a wire provided with a connecting ring at at least one of opposite ends of the wire, with a turn buckle provided at an end of the wire such that the replacement base is horizontally mounted.
10. The module replacement device of claim 4 , wherein the support member comprises:
a wire provided with a connecting ring at at least one of opposite ends of the wire, with a turn buckle provided at an end of the wire such that the replacement base is horizontally mounted.
11. The module replacement device of claim 5 , wherein the support member comprises:
a wire provided with a connecting ring at at least one of opposite ends of the wire, with a turn buckle provided at an end of the wire such that the replacement base is horizontally mounted.
