本实用新型涉及一种电力设备的检测系统，尤其涉及一种电力设备的噪声和电磁场同步检测系统。 The utility model relates to a detection system of electric equipment, in particular to a synchronous detection system of noise and electromagnetic field of electric equipment. the
背景技术Background technique
随着城市建设的发展，工业和居民用电量逐渐增高。变电站和高压线路的负荷增大，噪声和电磁场强度加剧。加之社会公众对环保日益关注，变电站和高压线路的噪声及电磁场强度经常成为环保投诉的焦点，公众对电力噪声和电磁场强度标准一直缺乏了解途径，电力部门通常接到投诉后才采取措施和解释工作，工作效果往往不明显。 With the development of urban construction, industrial and residential electricity consumption is gradually increasing. The load on substations and high-voltage lines increases, and the noise and electromagnetic field intensity intensify. In addition, the public is increasingly concerned about environmental protection. The noise and electromagnetic field strength of substations and high-voltage lines often become the focus of environmental protection complaints. The public has always lacked a way to understand the standards for power noise and electromagnetic field strength. The power department usually takes measures and explains the work after receiving complaints. , the working effect is often not obvious. the
目前电力设备的噪声及电磁场的检测一般通过噪声检测设备和电磁场检测设备来完成，虽然目前噪声检测设备和电磁场检测设备逐渐趋于小型化和智能化，携带检测效率都得到了提高，但是这种传统的检测方式对噪声和电磁场分别进行检测，或先或后，虽然可以同时进行检测，但是这样花费极大的人力，而且目前的手段只能停留在表面的数据分析，然而不能够及时地反映给监管中心和公众，延时严重，不能及时处理异常状况；这些检测数据只能对于电力部门内部的工作人员公开，为其工作提供一定的参考，但是公众向想了解电力设备噪声及电磁场的相关信息则即为困难，不利于噪声及电磁场数据的公开化，透明化，造成部分公众的心理恐慌；某些变电站由于人力的限制，只能应付日常供电工作，对于电力设备产生的噪声以及电磁场更是疏于检测，不能通过这些重要数据作为工作指导，严重影响周围居民的安全，引起电力设备周围的居民的恐慌。 At present, the detection of noise and electromagnetic field of power equipment is generally completed through noise detection equipment and electromagnetic field detection equipment. The traditional detection method detects the noise and the electromagnetic field separately, or first or later. Although it can be detected at the same time, it takes a lot of manpower, and the current means can only stay in the data analysis of the surface, but cannot reflect in time. For the supervision center and the public, the delay is serious, and abnormal conditions cannot be dealt with in time; these detection data can only be disclosed to the staff in the power department to provide a certain reference for their work, but the public wants to know about the noise of power equipment and the electromagnetic field. Information is difficult, which is not conducive to the openness and transparency of noise and electromagnetic field data, causing psychological panic among some public; due to manpower constraints, some substations can only cope with daily power supply work, and the noise and electromagnetic fields generated by power equipment are even more difficult. It is negligence in detection, and these important data cannot be used as work guidance, which seriously affects the safety of surrounding residents and causes panic among residents around electric equipment. the
因此，需要提供一种电力设备的噪声和电磁场的检测系统，能够对各检测点的电力设备产生的噪声以及电磁场进行实时同步检测，并且及时地将检测数据同步传输到数据监控中心，有效降低人力成本，大大提高响应速率，并能够使公众及时地了解自身所在检测点的噪声及电磁场的变化状况。 Therefore, it is necessary to provide a noise and electromagnetic field detection system for power equipment, which can detect the noise and electromagnetic field generated by the power equipment at each detection point synchronously in real time, and transmit the detection data to the data monitoring center in a timely manner, effectively reducing manpower. The cost is greatly improved, and the response rate is greatly improved, and the public can keep abreast of the noise and electromagnetic field changes at the detection point where they are located. the
