地下高压电力线
摘要：
本发明涉及一种地下三相高压电力线，该电力线包括三相导电电缆，所述导电电缆中的每一条都由通过交联接点(4)互连的一系列电缆部分(3a、3b)构成，包括连接至第一电缆部分(3a)的屏蔽层和第二对接电缆部分(3b)的屏蔽层的连接接口(7)、以及具有接点扩展箱(14)并配有连接至每个接点的连接接口(7)的附加连接接口(8)的模块(6)。根据本发明，避雷器(10)布置在所述模块(6)中，并电连接至模块的所述附加连接接口(8)，所述避雷器(10)配有用于监测其在连接至信号发生器(16)的所述箱(14)中的状况的装置。
摘要（英）：

An underground, three-phase, high-voltage electrical line, includes three phase-conducting cables, each being made up of a succession of cable portions (3a, 3b) interconnected by a cross-bonding junction (4). The line has a connection interface (7) connected to the screen of a first cable portion (3a) and to the screen of a second butted cable portion (3b), a module (6) provided with a junction extension box (14) and equipped with an additional connection interface (8) connected to the connection interface (7) of each junction. A lightning arrester (10) is disposed in the module (6) and is electrically connected to the additional connection interface (8) of the module and the lightning arrester (10) is equipped with a device to monitor its condition disposed in said box (14) connected to a signal generator (16).
