Abstract

In this embodiment, a case in which an igniter provided with a power cable is inserted inside; And a clamp provided on the outside of the case so as to be mounted on a cable tray for guiding the power cable.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an igniter plug type spark plug type igniter,

The present invention relates to a spark plug type igniter test apparatus. More particularly, the present invention relates to a spark plug type igniter testing apparatus capable of inspecting a high-temperature spark plug type igniter safely and quickly.

Conventionally, in order to inspect and test a spark plug type igniter included in a gas turbine, a rubber plate is laid on a top plate of a gas turbine, and an igniter is drawn thereon, .

In the above-mentioned manner, the work space is narrow due to the outer shape of the rounded gas turbine, so that only about one to three igniters can be operated at the same time.

In addition, since the igniter is already heated when the gas turbine is started, the rubber plate melts due to the temperature of the igniter during use, and the melted rubber is transferred to the igniter.

In addition, fire safety gloves worn for the safety of workers are also melted by the temperature of the igniter, thereby causing problems such as burning of the hands of the operator.
