The existing means for checking switch quantity circuits are relatively single, unable to simultaneously conduct linkage checks on multiple switch quantity signal circuits and unable to visually and reliably monitor. Moreover, due to the relatively dense arrangement of terminal blocks, there is a risk of accidentally disconnecting the wiring during the test in poor lighting conditions. And during the test, due to the need to disconnect and reconnect the wiring multiple times, it will cause damage to the terminal block and reduce the test efficiency. Summary of the Invention
[0003] The object of the present invention is to provide a relay switch quantity linkage and opening / closing monitoring device that is more convenient and efficient to use in view of the above deficiencies.
[0004] The technical solution of the present invention is: a relay switch quantity linkage and opening / closing monitoring device, which is characterized in that it includes a fixed plate frame, multiple opening / closing connection pieces and name tags are respectively fixed on the fixed plate frame in sequence. The fixed plate frame is fixed on the protection device to be calibrated by means of screw fastening through the plate frame fastening bolt holes. The connection piece terminals are connected to the positive and negative potential ends of the switch quantity through flexible wires and are equipped with LED indicators.
[0005] In the above solution, it further includes: The opening / closing connection piece is detachably connected to the fixed plate frame.
[0006] At least six or more opening / closing connection pieces are provided on the fixed plate frame, and the connection pieces are arranged at intervals.
[0007] The advantages of the present invention are: 1) This device can be applied to various models of protection devices, and the fixing screw holes at the four corners are convenient for fixing.
[0008] 2) This device can simultaneously conduct action tests on multiple groups of switch quantity signals and can realize random combination tests of multiple groups of switch quantity signals, facilitating the simulation of the interlocking test conditions of the protection device under different states, avoiding the trouble of repeatedly disconnecting and reconnecting the wiring, and greatly improving the calibration speed and accuracy.
[0009] 3) Setting name tags can effectively distinguish and prevent accidental disconnection of wiring when multiple groups of switch quantities are tested simultaneously.
[0010] 4) Install a detachable indicator light at one end of the terminal block to monitor the on / off status of the switch quantity circuit through the indicator light.
[0011] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Description of the Drawings
[0012] Figure 1 is a front structural schematic diagram of the present invention.
[0013] Figure 2 is a back structural schematic diagram of the present invention. Specific Embodiments
[0014] Refer to Figure 1 and 2 , the names of the components are as follows: fixed plate frame 1, plate frame fastening bolt hole 2, on-off connecting piece 3, connecting piece terminal 4, name tag 5, flexible wire 6, LED indicator light 7.
[0015] Refer to Figure 1 and 2 , the relay switch quantity linkage and on-off monitoring device includes a fixed plate frame 1, and multiple on-off connecting pieces 3 and name tags 5 are respectively fixed on the fixed plate frame 1 in sequence, that is, there are at least six or more on-off connecting pieces 3 on the fixed plate frame 1 ( Figure 1 nine in ), and each of the connecting pieces is arranged at intervals. The fixed plate frame 1 is fixed on the protection device to be calibrated by means of screw fastening through the plate frame fastening bolt hole 2, and the on-off connecting piece 3 is detachably connected to the fixed plate frame 1. The connecting piece terminal 4 is connected to the positive and negative potential ends of the switch quantity through the flexible wire 6 and is equipped with an LED indicator light 7 for monitoring the on-off of the switch quantity signal circuit.
[0016] Usage method: On-site, the fixed plate frame 1 is reliably fixed on the protection device to be calibrated at the plate frame fastening bolt hole 2 by means of bolt fastening for positioning, which can prevent the device from falling off during calibration. Mark the specific name of the switch quantity to be tested on the name tag 5 below the on-off connecting piece 3; both ends of the connecting piece terminal 4 are connected through the flexible wire 6, where one end of the flexible wire 6 is directly connected to the positive potential terminal of the switch quantity, and the other end is first connected to the LED indicator light 7 and then to the negative potential terminal of the switch quantity. In this way, by separating and combining different connecting pieces, the combination and calibration of different switch quantity circuits can be realized, and whether the on-off action is in place can be monitored by whether the LED indicator light 7 lights up reliably. This device can realize the simultaneous control of multiple groups of switch quantities. For protection devices with working condition requirements, the switch quantities can be combined arbitrarily to ensure meeting the calibration conditions, avoiding the trouble of repeated disconnection and connection of wires, and greatly improving the calibration speed and accuracy.
