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
本实用新型属于继电保护技术领域，特别涉及一种继电保护二次回路测试装置。 The utility model belongs to the technical field of relay protection, in particular to a secondary circuit test device for relay protection.
背景技术 Background technique
随着经济发展和人民生活水平的提高，用电需求量迅速增长，有效地提高保护装置定检效率，缩短设备停电时间成为了提高电力系统供电可靠性，提升供电服务质量，增加有效供电量的重要手段。传统的试验装置，每次只能检验一到两个节点或回路，检验项目多时，继电保护试验人员必须在保护屏内频繁拆接线，增加了接线失误率。试验过程中，需要配合的技术人员多，工作的繁杂性也使得定检工作中难免发生漏检，少检，重复检验的现象，导致保护功能测试时间长，最终的结果是工作效率低，设备停电时间长，无法符合人们对电力企业可靠供电的要求。 With the economic development and the improvement of people's living standards, the demand for electricity has grown rapidly. Effectively improving the efficiency of regular inspections of protective devices and shortening the power outage time of equipment has become the key to improving the reliability of power supply in the power system, improving the quality of power supply services, and increasing the effective power supply. important means. Traditional test devices can only test one or two nodes or circuits at a time. When there are many test items, relay protection testers must frequently disconnect the wiring in the protection screen, which increases the wiring error rate. During the test process, many technicians need to cooperate, and the complexity of the work also makes it inevitable that missed inspections, less inspections, and repeated inspections will occur in the regular inspection work, resulting in a long time for the protection function test. The final result is low work efficiency and equipment failure. Long power outages cannot meet people's requirements for reliable power supply from power companies.
