Description

검전장치{voltage detector}Voltage detector

본 발명은 검전장치에 관한 것으로, 더 상세하게는 통전여부에 따라 회전부재가 회전하는 구조를 가지는 검전장치에 관한 것이다. The present invention relates to an inspection apparatus, and more particularly, to an inspection apparatus having a structure in which a rotating member rotates according to whether electricity is supplied.

일반적으로 종래의 전기설비화재에 대한 감지는 발열이 진행되어 화재 전의 연기에 의해서 동작하는 연기감지장치와 완전발화상태에서 감지하여 외부로 알려주는 화재상태 감지장치들이 대부분을 이루고 있었다. 전동기 제어반 내부기기들의 이상 유무상태를 확인하기 위해서는 직접 각 유니트의 내부를 살펴봐야 하In general, the detection of a conventional electrical equipment fire was made of a smoke detection device operating by the smoke before the fire and the fire state detection device to detect in the complete ignition state to inform the outside. In order to check the status of equipment inside the motor control panel, you have to inspect the inside of each unit.

는 번거로움이 있었으며, 수시로 감시할 수는 없다는 문제점이 있었다. 전동기 제어반의 메인차단기나 각전동기용 유니트에 접속되는 주전원을 공급하는 모선부스바가 종래의 동(Cu)부스바로써 전동기의 용량이나 수량에 따라 전류량이 증가하므로 당연히 두께와 넓이가 큰 동부스바를 사용하게 되므로 경제적 손실은 물론이고 설비의 중량증가가 심화되어 이동설치나 건물하중에도 영향을 끼치며 가공공정에도 어려움이 따르는 문제점이 있었다.Was troublesome, and there was a problem that can not be monitored from time to time. Bus bus bar supplying main power connected to main circuit breaker of motor control panel or each motor unit is conventional copper bus bar. Current amount increases according to the capacity and quantity of motor. As a result, the economic loss, as well as the weight increase of the facility is intensified, affecting the mobile installation or building load, and also had a problem in the machining process.

특히, 전기 설비나 가전기기 등에 있어서는, 부하의 증대나 접촉 불량 혹은 누전 등에 의해 과전류가 흘러 기기의 온도가 이상하게 높아지면, 이것이 원인으로 고장을 일으키거나 과열 사고를 초래할 우려가 있다. Particularly, in an electrical installation or a home appliance, if an overcurrent flows due to an increase in load, poor contact or a short circuit, etc., the temperature of the device becomes abnormally high, this may cause a failure or an overheating accident.

이러한 점을 감안하여 로 발열이 예상되는 부위에 대해 전기 열 저항형의 온도 센서 등을 미리 설치해 두고, 경고음 등에 의해 이상 발열 현상의 발생을 알리는 방법도 고려된다. 그러나, 이와 같은 온도 센서는 일반적으로 고가이고, 게다가 그 설치시에는 많은 온도 센서나 배선 및 경보 기기 등을 부설할 필요가 있으므로, 비용의 면에서 실용적이지 않다.In view of this, a method of pre-installing an electric heat resistance type temperature sensor or the like in a site where furnace heat is expected to be generated is also considered. However, such a temperature sensor is generally expensive, and since it is necessary to install many temperature sensors, wirings, alarm devices, etc. at the time of installation, it is not practical in terms of cost.

그로 인해, 최근에는 알코올류 등의 냄새 발생 물질을 수지로 된 캡슐이나 수지 테이프 또는 튜브 내에 봉입하여, 이것을 발열이 예상되는 부위에 미리 설치해 두고, 발열에 의해 냄새 발생 물질을 봉입하고 있는 캡슐 등이 녹으면 내부의 냄새 발생 물질이 발산되므로, 그 냄새의 유무를 근처에 있는 사람이 직접 혹은 가스 검출 장치 등을 이용하여 간접적으로 감지함으로써 이상 과열 현상의 발생을 검지하는 방법이 일본 특허 공개 평5-18831호, 일본 특허 공개 평6-66646호, 일본 특허 공개 평6-66647호에 개시되어 있다. Therefore, in recent years, capsules containing odor generating substances such as alcohols are encapsulated in resin capsules, resin tapes or tubes, and pre-installed at sites where heat is expected to be generated. When melted, an odor generating substance is emitted, so a method of detecting abnormal overheating phenomenon by detecting nearby odors directly or indirectly using a gas detection device is disclosed. 18831, Japanese Patent Laid-Open No. 6-66646, and Japanese Patent Laid-Open No. Hei 6-66647.

그러나 이러한 방법은 한번 사용 후 다시 사용할 수 파손되지 않은 캡슐을 다시 설치하여야 하는 번거로움이 있다. However, this method is cumbersome to reinstall the unbroken capsule that can be used again after use.

본 발명은 상술한 바와 같은 문제점을 해결하기 위한 것으로, 발열 또는 통전 여부의 시인성을 향상시킬 수 있으며, 반복 사용이 가능한 검전장치를 제공함에 그 목적이 있다.
