Description

Lightning protection branching cabinet Technical Field The invention relates to the field of railway branching cabinets, in particular to a lightning protection branching cabinet. Background In places such as railways where a large number of signal cables exist, the signal cables are often required to be separated, and specifically, each wire core of the signal cables is connected into a separated time terminal respectively, separated time is performed through the separated time terminal and connected with a surge protector, lightning protection is achieved at the same time, in order to achieve the functions, a lightning protection separated time cabinet is usually required to be placed in a railway signal mechanical chamber, and the main function of the lightning protection separated time cabinet is to perform switching and distribution of the indoor and outdoor signal cables, namely to reduce or reduce lightning electromagnetic pulse intensity which is conducted into the signal mechanical chamber through the outdoor signal cables. The lightning protection junction box consists of a cabinet, a junction terminal, a surge protector, a grounding busbar and related accessories. Because the branching operation to the signal cable involves the cable layout in the cabinet body before and after branching, lightning protection also involves the cable layout between branching terminal and surge protector and the earth cable, namely there are two kinds of cables of branching cable and lightning protection cable in the cabinet body, therefore the cable quantity in the cabinet body is more, can cause the cable mutual influence in the cabinet body, be convenient for the operator to carry out the cable operation that the branching terminal is correlated with alone, or carry out the cable operation that the surge protector is correlated with alone.
