The secondary circuit terminal block is one of the connection elements of the electrical cabinet, which establishes a connection between the element and the equipment by means of contact points (e.g. cable connection terminals on the electrical cabinet), and then establishes a connection between the equipment and the system, and between the system and the system, through various interfaces. In the application of the power system, the conventional connection establishes a connection between the terminal and the protection device from the cable connection terminal on the electrical cabinet by means of the contact point, and then establishes a connection between the protection device and the circuit breaker mechanism through the connection interface of the protection device.
The periodic inspection task of the relay protection and measurement and control screen cabinet is heavy, potential safety hazards exist in the test and field operation of the terminal strip, and the following problems are faced:
(1) the testing and maintenance work steps of the secondary circuit are complex, the field inspection frequency of the relay protection device is high, the workload is huge, manual wiring is performed, and the work efficiency of wire disconnecting and checking is extremely low.
(2) The terminal row return circuit is more, and the mistake bumps easily appear in the hot-line work process, and the operation mode of point-to-point access can't satisfy the system operation and maintenance requirement of high reliability, easily causes the potential safety hazard.
(3) Conventional terminal block testing methods lack effective means for definition and evaluation.
It is necessary to design a new electrical connection device to meet the actual requirements.
SUMMERY OF THE UTILITY MODEL
In view of the above, the utility model provides an integral anti-drop current test plug which can well meet the actual current test requirement.
The utility model provides an integral anti-drop current test plug, has insulating casing, and equidistant distribution has a plurality of equidimension contact pins on the casing, and the top of contact pin has the line chamber of holding of indent, holds and is provided with locking screw on the line chamber, can insert the peeled examination of awaiting measuring cable of end in holding the line intracavity, awaits measuring the cable and is connected with the contact pin electricity, and locking screw can support tightly on the insulating epidermis of the examination of awaiting measuring cable, prevents to await measuring the cable from holding the line intracavity and drop.
The contact pin be the lantern spring contact pin, can prevent effectively that the contact pin from falling from the jack is interior accident.
One side of the shell is provided with an extended guide limiting groove for preventing the insertion direction error of the contact pin.
The number of the pins is 2-8, preferably 4.
The surface of the shell is provided with anti-slip lines for preventing slipping when holding.
The cable to be tested is a commercial electric wire.
The utility model can realize integral multi-path test for the current terminal loop. Connecting a test signal to the secondary side of a relay protection device through a multi-path contact pin by using a secondary current loop integral test plug metal part of a relay protection cabinet, so that a field secondary relay protection loop enters a test state; after the contact pin is pulled out, the secondary side loop is disconnected with external test equipment, so that the overall test of the secondary loop during test wiring is realized, and the field test efficiency is improved.
The utility model has a compact structural design, which has the following advantages.
1) The contact pin and the casing fixed connection of current sampling, the direction spacing groove corresponds with the test hole of waiting to test the terminal for the direction when the test is pulled out and is inserted.
2) The contact pin is a lantern spring contact pin to realize the automatic locking function of the test. The lantern spring contact pin can realize automatic resilience when the plastic clamping pin is inserted, and abuts against the testing hole of the base to form a closed loop.
3) The contact pin belongs to a screw connection type fixed type, the shell is provided with a wire accommodating cavity, external wiring is realized, and the function of self short circuit can be realized besides the normal plugging function.
4) The structure design is simple and reliable, the assembly is simple, the use is convenient, and the product cost is effectively reduced.
