Title:
MULTIPATH ELECTRIC POWER METERING JUNCTION BOX
Document Type and Number:
WIPO Patent Application WO/2016/177289
Kind Code:
A1
Abstract:
Disclosed is a multipath electric power metering junction box. At least two upper terminal blocks (4, 5) and at least two interconnected lower terminal blocks (7, 8) are disposed on a voltage wiring board (2), and the lower terminal blocks (7, 8) and the upper terminal blocks (4, 5) are connected with each other respectively through voltage linkage plates (9, 10), so as to form at least two voltage circuits connected in parallel. Thus, the purpose is achieved that the voltage circuit per phase is divided into multipath independent outputs on at least two paths. A first normally-on connection terminal (11), a second normally-on connection terminal (12), a third normally-on connection terminal (13), as well as a first upper connection terminal (14) and a second upper connection terminal (15) connected with each other, are disposed on a current wiring board (3), the first normally-on connection terminal (11) and the second normally-on connection terminal (12) are connected with each other through a first current linkage plate (16), the first upper connection terminal (14) is provided with a second current linkage plate (17) and a third current linkage plate (18); a load control terminal is capable of metering normally when an electric power meter is replaced in a loaded state, or the electric power meter is capable of metering normally when the load control terminal is replaced in a loaded state, giving more accuracy in electric power metering.
