Abstract

An arc eliminator includes a housing having a space formed therein and including an opening, an arc extinguishing part installed in the housing and including a moving rod disposed to be movable to the space, an indicator rotatably installed within the housing and seen through the opening, and an indicator rotating mechanism interworking with the moving rod when the moving rod moves, to rotate the indicator. A closing state and opening state of an arc extinguishing part may be easily recognized through an indicator and an arc accident may be minimized.

First claim

What is claimed is:

1. An arc eliminator comprising:
a housing having a space formed therein and including an opening;
an arc extinguishing part installed in the housing and including a moving rod disposed to be movable to the space;
an indicator rotatably installed within the housing and seen through the opening; and
an indicator rotating mechanism interworking with the moving rod when the moving rod moves, to rotate the indicator.

2. The arc eliminator of claim 1 , wherein the indicator includes:
a first indicator seen through the opening when the moving rod moves toward the outside of the arc extinguishing part; and
a second indicator seen through the opening when the moving rod moves toward an interior of the arc extinguishing part.

3. The arc eliminator of claim 2 , wherein
the indicator is configured as a polyhedron,
the first indicator is formed on a first surface of the polyhedron, and
the second indicator is formed on a second surface of the polyhedron perpendicular to the first surface of the polyhedron.

4. The arc eliminator of claim 1 , wherein the indicator is positioned on a rear side of the opening.

5. The arc eliminator of claim 1 , wherein the indicator rotating mechanism includes:
a rotary link rotatably supported in the housing and rotated centered around a first rotational shaft when the moving rod moves; and
a connection link connected to the rotary link and moving forwards and backwards when the rotary link rotates, and connected to the indicator by a second rotational shaft to rotate the indicator.

6. The arc eliminator of claim 5 , wherein a first rotational shaft supporter having a through hole formed to allow the first rotational shaft to rotatably penetrate therethrough is disposed within the housing.

7. The arc eliminator of claim 5 , wherein the moving rod includes:
a rod disposed to move forwards and backwards in the arc extinguishing part; and
a contact body installed on one side of the rod and contacting the rotary link.

8. The arc eliminator of claim 7 , wherein the rotary link includes:
a first link portion installed in the first rotational shaft and contacting an outer end of the contact body; and
a second link portion installed in the first rotational shaft and allowing the connection link to be connected thereto.

9. The arc eliminator of claim 5 , further comprising:
a support installed in the housing and rotatably supporting the indicator.

10. The arc eliminator of claim 9 , further comprising:
an elastic member connected to the support and a connection shaft.

11. The arc eliminator of claim 10 , wherein the support includes an elastic member connection shaft to which one end portion of the elastic member is connected.
