Problems solved by technology

Another example is the Chinese invention patent (patent number: 201310447177.1), a combined short-circuit terminal block for secondary terminals, which is only suitable for short-circuiting adjacent continuous terminals, and the connection between the terminal blocks relies on elastic copper sheets, which frequently After use, there may be poor contact of the plug due to deformation and fracture of the copper sheet, and the reliability is not high.
Another example is the Chinese invention patent (patent number: 201410454227.3) for short-circuit terminals and short-circuit terminal blocks, including connection seats and conductive rods. The slots are plugged in sequence, and it is not compatible with the current test wire. It can only be used when shorting the terminals on one side of the terminal block, and the scope of use is limited.

Embodiment approach 1

[0030]A complete set of modular and combinable standard current terminal shorting tools. This set of tools consists of four modules: A module, B module, C module and D module. The A module consists of Ⅰ outer insulating shell 1, lower metal plug 2, Upper metal plug 3, I metal connecting jack 4, I internal conductive core 5, B module consists of II outer insulating shell 6, upper metal plug 3, II metal connecting jack 7, I inner conductive core 5, C module consists of Ⅲ External insulating shell 8, lower metal plug 2, Ⅰ metal connecting jack 4, module D is composed of Ⅳ outer insulating shell 9, lower metal plug 2, Ⅰ metal connecting jack 4, Ⅱ metal connecting jack 7, Ⅱ internal conduction core 10; the diameter of the lower metal plug 2 should match the jack of the standard current terminal for connecting the standard current terminal, and the diameter of the upper metal plug 3 is the same as that of the lower metal plug 2 for connecting other modules; The upper ends of I metal...

Embodiment approach 2

[0032] When short-circuiting non-adjacent standard current terminals, in the case of module combination, several A modules, several B modules and one C module are required for short-circuiting. When A module is connected to B module, the upper metal plug 3 of A module needs to be inserted into a B module. II metal connection jack 7, when B module is connected to B module, the upper metal plug 3 of B module needs to be inserted into the II metal connection jack 7 of another B module, and B module needs to be connected to A module (or C module). Insert the upper metal plug 3 of an A module (or C module) into the I metal connection jack 4, and the insertion method between other modules is the same as that of the specific embodiment one. According to the standard current terminals that need to be short-circuited, the module corresponding to the standard current terminal that does not need to be short-circuited when plugging in the module is the B module, and the rest correspond to ...

Embodiment approach 3

[0034] The combination of modules when shorting the standard current terminals on different sides. In this mode, several A modules and D modules are required for short-circuiting. When A module is connected to D module, the upper metal plug 3 of A module needs to be inserted into the II metal connection jack 7 of D module. The plugging between A modules is similar to the specific implementation method. one. According to the standard current terminals that need to be short-circuited, the module corresponding to the terminal that is not on the side of the other standard current terminals when plugging in the module is the D module, and the rest correspond to the A module, thus forming an electrical connection across both sides of the terminal block Parts, and finally several lower metal plugs 2 of this complete connector are inserted on the terminals to be shorted and completed. The I metal connection jack 4 in the D module can be used to expand other modules, and the plug-in o...

Abstract

The invention provides a whole set modular composable standard current terminal short circuit tool which belongs to the technical field of electrical engineering. The tool is a modular short circuit tool specially designed for the secondary circuit standard current terminal of relay protection of a substation. The short circuit tool comprises four different modules of an A module, a B module, a C module and a D module. Four modules are inserted and freely combined into a complete electrical connector, so as to meet three basic and even more complex short circuit requirements on both sides of adjacent standard current terminals, non-adjacent standard current terminals and a standard current terminal bar in the field. The electrical connector is directly inserted into the current terminal bar to realize short circuit of a current secondary circuit. According to the invention, the whole set modular composable standard current terminal short circuit tool has the advantages of convenient and flexible use and reliable electrical connection; the appearance of the combined electrical connector is neat and compact; and the influence of the field work on current short circuit is effectively avoided.

Description

technical field [0001] The invention discloses a complete set of modularized and combinable standard current terminal short-circuiting tools, belonging to the technical field of electrical engineering, in particular to an electrical connection tool, which is specially aimed at the short-circuiting tool of standard current terminals in secondary circuits of substation relay protection. Background technique [0002] Substation relay protection will involve a lot of maintenance or expansion work related to the reconnection of the current secondary circuit, such as the replacement of current transformers, the replacement of synchronous vector measurement devices, and the transformation of stability control systems. When reconnecting the secondary circuit of the current, especially when reconnecting without power failure at intervals, in order to prevent the secondary side of the current transformer from being open, it is necessary to short-circuit the secondary circuit of the cur...
