Embodiment

[0034] A modular relay routing device provided in this embodiment includes:

[0035] The insulation test host includes several first selectors, and each first selector is connected to the insulation test cable; the leakage test host includes several second selectors, and each second selector is connected to the leakage test cable; The switch is connected with the insulation test host and the leakage test host. Wherein, the first route selector and / or the second route selector includes: several route selection boards, which are arranged in multiple stages, wherein the multi-channel input of the Nth stage route selection board is output to the N+1th stage after being routed One of multiple input ports on the board.

[0036] Specifically, such as figure 1 As shown, during the test of the insulation and leakage current hosts, the circuit selection board is required to select the route. There is no difference in the circuit selection board used. The number of boards can be flexib...

Abstract

The invention relates to a routing device, in particular to a modular relay routing device. Including: insulation test host, including several first selectors, each first selector connected to insulation test cables; leakage test host, including several second selectors, each second selector connected to leakage test cable. Therefore, the present invention has the following advantages: the design of the board card of the route selection module integrates the functions, the board card adopts a modular design, and the installation and maintenance are convenient and quick. Each board uses 5 safety relays to realize more routing functions and meet the requirements of miniaturization design. Boards are installed in a chassis, and the number of cables is only related to the number of boards, which no longer affects the space and layout in the cabinet.

Description

technical field [0001] The invention relates to a routing device, in particular to a modular relay routing device. Background technique [0002] The microcomputer centralized monitoring system has the functions of insulation test and leakage test. The insulation test is the measurement of the insulation resistance of the signal cable, which can timely understand the condition of the cable insulation, understand the status of the signal circuit, and ensure the normal operation of the equipment. The leakage current test is a test of the current of the power line to the ground. It can know whether each power line is damaged or grounded, and detect line faults in time. [0003] Before the insulation or leakage test, it is necessary to select the cable route. The route selection is a very important unit in the centralized monitoring system. It is necessary to select the cable to be tested through a multi-level relay. In the end, only one cable is selected, and the tested line T...
