Abstract
The utility model relates to an insulating test box which includes a box body. The box body is provided with a low of wiring conversion terminals. The low of wiring conversion terminals are provided with a row of switches correspondingly connected with the wiring conversion terminals. An insulating test table which is connected in parallel with the switches is arranged below the low of switches. The insulating test table is connected with a grounding switch. The grounding switch is connected with a grounding point. The novel insulating box can realize the simultaneous testing of multiple sub-paths, thus avoiding the frequent test line connection changes. The novel insulating box can also realize the functions of the grounding testing and the testing among sub-paths. The beautiful and practical novel insulating test box can reduce the workload and has the advantages of high integration level, easy operation, and high security.
Description
Technical field
The utility model relates to a kind of Insulation test case.
Background technology
It is extremely important to do the secondary Insulation test in transformer station.Traditional insulation tester is just drawn two lead-in wires from the gauge outfit binding post, must one the tunnel one the tunnel when test is insulated along separate routes cuts to change; Traditional insulation tester is because of pursuing branch testing, and the test duration is longer; During the work of tradition insulation tester, the test wire that the scene need be carried, material, instrument is scattered, and integrated level is lower.
The utility model content
The purpose of the utility model just is to provide a kind of novel Insulation test case, and it can realize many together tests along separate routes, avoids frequent reconfiguration test wire; Through change-over switch can realize testing over the ground and along separate routes between the function of test, need not change after test wire connects; Test wire, material and instrument etc. all concentrate in the Insulation test case, and integrated level is high, and is both artistic and practical; Simple to operate, alleviated workload, through change-over switch over the ground, realize discharge over the ground, security is improved.
The technical scheme of the utility model is: the utility model comprises casing; On casing, be provided with row's wiring conversion terminal; Be provided with the corresponding row's change-over switch that connects at row's wiring conversion terminal with the wiring conversion terminal; Have an Insulation test table parallelly connected with above-mentioned each change-over switch in row's change-over switch, said Insulation test table is connected with a ground connection change-over switch, and the ground connection change-over switch connects earth point.
The utility model can realize that through the wiring connecting column a plurality of loops together test; Realize handoff functionality through two-way on-off switch (upwards being " test along separate routes ", is " test over the ground ", and middle is " exit status ") downwards; Test and discharging function over the ground between realizing along separate routes through the ground connection change-over switch.
The beneficial effect of the utility model is: the utility model can be realized many together tests along separate routes, avoids frequent reconfiguration test wire; Through change-over switch can realize testing over the ground and along separate routes between the function of test, need not change after test wire connects; Test wire, material and instrument etc. all concentrate in the Insulation test case, and integrated level is high, and is both artistic and practical; Simple to operate, alleviated workload, through change-over switch over the ground, realize discharge over the ground, security is improved.
Description of drawings
Fig. 1 is the said novel Insulation test box of a utility model embodiment back synoptic diagram.
Embodiment
The utility model embodiment comprises casing 7 shown in accompanying drawing; On casing 7, be provided with row's wiring conversion terminal 1; Have and the wiring conversion terminal 1 corresponding row's change-over switch 2 that connects at row's wiring conversion terminal 1; Having an Insulation test table 3 parallelly connected with above-mentioned each change-over switch in row's change-over switch 2 is a kind of ohmmeter, and said Insulation test table 3 is connected with a ground connection change-over switch 6 through connecting groove 4, and ground connection change-over switch 6 connects earth point 5.
The novel Insulation test case of the utility model is on-the-spot when using, and is connected to the terminal place that institute will test insulation component or cable through connection terminal 1, again through the change-over switch 2 realization insulation against ground tests of Insulation test case or the insulation situation between the components and parts.
As when testing over the ground, should be connected to extraneous ground connection place through earth point 5.Be connected to conducting state through ground connection change-over switch 6 and earth point, change-over switch 2 switches to and ground connection change-over switch 6 conducting states, realizes the test over the ground of components and parts through the Insulation test function of Insulation test table 3.
When testing between each components and parts or the cable, reliably break off through ground connection change-over switch 6 and earth point 5.Two connection sides that change-over switch 2 switches to Insulation test table connecting groove 4 to the components and parts that will test or cable, the Insulation test function through Insulation test table 3 realize components and parts between test.
The substation secondary Insulation test, the project of main test has: (1) protection loop; (2) control loop; (3) signal circuit; (4) current return; (5) voltage circuit.
Claims (1)
1. Insulation test case; It is characterized in that: comprise casing; On casing, be provided with row's wiring conversion terminal, be provided with the corresponding row's change-over switch that connects, have an Insulation test table parallelly connected with above-mentioned each change-over switch in row's change-over switch with the wiring conversion terminal at row's wiring conversion terminal; Said Insulation test table is connected with a ground connection change-over switch, and the ground connection change-over switch connects earth point.
