EXTENSION STATION CONTROLLER FOR DISTRIBUTION LINE AUTOMATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve weather-resistant properties and the noise-resistant properties of a distribution line automation system extension station controller. SOLUTION: A connector receptacle 10c, a connector plug 9c with a built-in photocurrent sensor signal processing unit which is connected to the connector receptacle 10c, a connector receptacle 10d and a connector plug 9d with a built-in photocurrent sensor signal processing unit which is connected to the connector receptacle 10d are provided in the housing of an extension station controller main part 3d. The connector plug 9c with a built-in photocurrent sensor signal processing unit has a built-in opto- electric conversion unit 6c and a built-in opto-electric conversion unit 7c, which are connected to photocurret sensor head units 4a through optical fiber cables 5c and a built-in photocurrent sensor signal processing circuit unit 8c by which signals from them are processed. The connector plug 9d with the built-in photocurrent sensor signal processing unit has a built-in opto-electric conversion unit 6d and a built-in opto-electric conversion unit 7d, which are connected to a photocurrent sensor head unit 4b through optical fiber cables 5d and a built-in photocurrent sensor signal processing circuit unit 8d by which signals from them are processed.
