Abstract
The invention provides a preparation method of a switching density relay test signal wire and belongs to the field of test signal wire preparation. When a 220KV SF6 switching density relay is examined by use of an existing calibration instrument, the test signal wire of the calibration instrument must be connected with the relay by use of a short circuit wire for examination, however, as the space of the signal contact portion of the inserted connector base of the relay in the method is small and the vision is poor, the problems of wrong insertion or plug breakage are prone to occur in the process of inserting the 6 signal jacks of the short circuit wire; the preparation method of the switching density relay test signal wire are used for solving the problems. Firstly, 6 tabs at one end of a 6-core strand wire are welded into an independent 6-core plug to form a 6-core plug of the test signal wire; secondly, the other end of the 6-core strand wire is connected to a connection formed in the frontage of the upper cover of the inserted connector of the relay according requirements, and then the upper cover of the inserted connector with the test signal wire is formed. The switching density relay test signal wire is mainly used for connecting the calibration instrument with the switching density relay.
Description
Technical field
The invention belongs to the preparation field of stimulus line.
Background technology
The process that former stimulus line connects, is specifically plugged into 1 → 4 corresponding with 5 connected → 7 see Fig. 1: 2 and is correspondingly plugged into 9;
1, during field test 220 kilovolts of switch density relays, need the plug-in connector upper cover on the right side of by density monitor to remove, expose 6 signalling contacts on plug-in connector base.
2, the stimulus line of tester extraction, directly can not be connected to 6 signalling contacts of relay, but by a shorting stub, is connected by stimulus line, connects loaded down with trivial details with relay.
3,6 core plugs of stimulus line are connected to the signal plug of tester, and the other end 6 fish mouth folders press from both sides side with shorting stub 6 fish mouths and are connected, and shorting stub opposite side 6 signal sockets are plugged on 6 signalling contacts of relay plug-in connector base respectively.
4, because space, relay plug-in connector base signalling contact place is little, sight line is bad, and during 6 signal socket grafting of shorting stub, easily make a mistake grafting or plug such as to fracture at the phenomenon.Causing can not accurate acquisition signal, or does not collect signal, repeatedly need carry out inflation/deflation to relay, and this will reduce relay useful life, extend test duration simultaneously.
Summary of the invention
The present invention is to solve existing tester to 220 kilovolts of SF
6when switch density relay verifies, a shorting stub must be passed through, the method that the stimulus line of tester and relay carry out being connected is verified, but because space, the method repeat circuit plug-in connector base signalling contact place is little, sight line is bad, during 6 signal socket grafting of shorting stub, the problem that easily make a mistake grafting or plug fracture.The invention provides a kind of preparation method of switch density relay stimulus line.
The preparation method of switch density relay stimulus line, the detailed process of the method is:
First, 6 the end of a thread of 6 core multi cord one end are welded in one independently in 6 core plugs, make 6 core plugs of stimulus line, and 6 core plugs of this stimulus line are used for being connected with tester signal plug;
Secondly, 6 the end of a thread of the 6 core multi cord other ends are connected alarm relay contact 1,2 respectively according to 1,2 contacts of tester, 3,4 contacts of tester connect the mode that relay latch contact 3,4 and 5,6 contacts of tester are connected relay latch contact 5,6 respectively respectively, receive the connection jaws place in the plug-in connector upper cover front of relay
Make the upper cover of the plug-in connector with stimulus line, and should be used for being connected with relay plug-in connector base with the upper cover of the plug-in connector of stimulus line, complete an one end with 6 core plugs, the other end is with the making of the stimulus line of the plug-in connector upper cover of relay.
The present invention makes a stimulus line that plug-in connector upper cover and base can be made to close be connected, and realizes tester holding wire and is directly connected with relay, reach fast, accurately, the reliable object connected.
The beneficial effect that the present invention brings is,
1, connect reliably, the originally connection of stimulus line, easily makes a mistake or contacts insecure, realizes now closed fast and accurately connection, ensure that the accurate of signals collecting.
2, save test duration, originally stimulus line connects needs 10 minutes repeatedly, only needs 2 minutes now, greatly increases operating efficiency.
