Patents
Search within the title, abstract, claims, or full patent document: You can restrict your search to a specific field using field names.
Use TI= to search in the title, AB= for the abstract, CL= for the claims, or TAC= for all three. For example, TI=(safety belt).
Search by Cooperative Patent Classifications (CPCs): These are commonly used to represent ideas in place of keywords, and can also be entered in a search term box. If you're searching forseat belts, you could also search for B60R22/00 to retrieve documents that mention safety belts or body harnesses. CPC=B60R22 will match documents with exactly this CPC, CPC=B60R22/low matches documents with this CPC or a child classification of this CPC.
Learn MoreKeywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.
Learn MoreChemistry searches match terms (trade names, IUPAC names, etc. extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS=) and similarity (use ~) searches are limited to one per search at the top-level AND condition. Exact searches can be used multiple times throughout the search query.
Searching by SMILES or InChi key requires no special syntax. To search by SMARTS, use SMARTS=.
To search for multiple molecules, select "Batch" in the "Type" menu. Enter multiple molecules separated by whitespace or by comma.

技术领域 technical field
本发明涉及电气设备领域，尤其涉及一种便携式多接头导线辊。 The invention relates to the field of electrical equipment, in particular to a portable multi-joint conductor roll.
背景技术 Background technique
在测试电压互感器和电流互感器的变比及误差时，需要用导线将互感器校验仪的测试端子、标准互感器和被测互感器的二次回路端子连接起来组成测试回路。试验用到的导线较多，且导线细长。假如测试完毕后不进行很好的整理，导线很容易缠绕绞合，不易分开，将很大程度上影响下次互感器测试的效率。另外在连接测试回路的过程中，需要将互感器校验仪的同一个测试端子用导线连到标准互感器和被测互感器的二次回路端子上，实现后两者二次回路的并联，用导线依次连接容易造成线路连接不清晰，万一连接错误，检查错接线将很困难。 When testing the transformation ratio and error of voltage transformers and current transformers, it is necessary to use wires to connect the test terminals of the transformer calibrator, the standard transformer and the secondary circuit terminals of the tested transformer to form a test circuit. There are many wires used in the test, and the wires are slender. If the test is not done well, the wires are easy to be twisted and twisted, and it is not easy to separate, which will greatly affect the efficiency of the next transformer test. In addition, in the process of connecting the test circuit, it is necessary to connect the same test terminal of the transformer calibrator to the secondary circuit terminal of the standard transformer and the measured transformer with wires, so as to realize the parallel connection of the secondary circuits of the latter two. Using wires to connect in sequence will easily cause the line connection to be unclear. In case of a wrong connection, it will be very difficult to check the wrong wiring.
