電氣安全概述
一、Electrical safety task :
1) to study various electrical accident and the mechanism of reasons, the patterns and characteristics and protective measures. (2) to study the use of electrical methods, electrical monitoring, Electrical inspection and electrical control methods to evaluate the safety of the electricity system and electricity proction solve the security problems.
二、Electrical Safety Work content :
1) Study and to take effective security measures.
(2) research and the dissemination of advanced electrical safety technology to improve electrical safety standards.
(3) Develop and implement technical standards for security and safety technology point of order.
(4) Establish and implement a safety management system.
(5) in the thinking of electrical safety and electrical safety ecation.
(6) analyze the case, find out the cause of the accident and the law.
三、Guarantee the security of electricity fundamentals :
(1) Electrical Insulation. Maintain distribution lines and electrical equipment in good insulation, is to guarantee personal safety of electrical equipment and the normal operation of the most basic elements. Electrical Insulation whether the performance of good, by measuring the insulation resistance, crushing strength, Leakage Current and dielectric loss, and other parameters measured.
(2) a safe distance. Electrical safety distance is the body charged objects close to the body, such as dangerous without the safety and reliability of distance. If body charged with the ground between the body charged with charged between, and the human body charged between body charged with other facilities and equipment between shall maintain a certain distance. Usually, the distribution lines and changes and distribution installations near work, it should consider a safe distance from the line that changed, Distribution Equipment safe distance, a safe distance from the maintenance and safe operation of distance.
3) safety carrying capacity. Conctor set the security flow is allowed to persist through the internal conctor CURRENT. Conctor sustained through the current security set excess flow, heat conctors will exceed the allowable values, damage to the insulation, even lead to leakage and fire. Therefore, in accordance with the security conctor containing a conctor cross section to determine flow and the selection of equipment is very important.
(4) signs. Clearly, accurate, uniform signs is to ensure that electricity security of the important factors. Generally, a color logo signs, badges and signs model markings, and so on. A different color marker nature of the different uses wire; General badges as a sign of dangerous places signs; Model equipment as a sign of special signs.
四、Security technology of electrical equipment basic requirements。 electrical accident statistics show that the electrical equipment as structural defects, installation of poor quality and can not meet the safety requirements caused by the large proportion of accidents. Therefore, in order to ensure personal safety and equipment safety, technical aspects of electrical equipment have the following requirements :
1) exposed on the ground and the personal touch easier Charged equipment, should take protective measures reliable.
(2) charged equipment and the ground and some other parts should be charged to maintain a safe distance.
(3) easy to over-voltage power system, there should be a lightning lightning line arrester, Protection gap voltage protection, and other devices.
(4) low voltage power system should be grounded, zero protection device.
(5) to all high voltage electrical equipment to be taken to install high voltage circuit breakers and fuses different types of protection measures; Low-voltage electrical equipment to be used with correspondingly low electrical protection measures for the protection.
(6) in electrical equipment, the siting of safety signs should be located.
(7) According to some electrical equipment characteristics and requirements, should take special security measures. 5, electrical accidents basic reasons for the classification and the classification by electrical accident occurred in the form of disaster can be divided into personal accident, equipment accident, the electrical fire and explosion accidents
By accident when the circuit conditions can be divided into short-circuit accidents, break accident, grounding accidents, leakage accident; according to the seriousness of the incident can be divided into serious accidents, serious accidents, incidents general; by the extent of injury. can be divided into death, serious injury, three minor injuries.

一、電氣安全工作的任務:
(1) 研究各種電氣事故及其發生的機理、原因、規律、特點和防護措施。
(2) 研究運用電氣方法,即電氣監測、電氣檢查和電氣控制等方法來評價電力系統的安全性和解決生產中用電的安全問題。
二、 電氣安全工作的內容
(1) 研究並採取各種有效的安全技術措施。
(2) 研究並推廣先進的電氣安全技術,提高電氣安全水平。 (3) 制定並貫徹安全技術標准和安全技術規程。
(4) 建立並執行各種安全管理制度。
(5) 開展有關電氣安全思想和電氣安全知識的教育工作。 (6) 分析事故實例,從中找出事故原因和規律。
三、 保證用電安全的基礎要素
(1) 電氣絕緣。保持配電線路和電氣設備的絕緣良好,是保證人身安全和電氣設備正常運行的最基本要素。電氣絕緣的性能是否良好,可通過測量其絕緣電阻、耐壓強度、泄漏電流和介質損耗等參數來衡量。
(2) 安全距離。電氣安全距離,是指人體、物體等接近帶電體而不發生危險的安全可靠距離。如帶電體與地面之間、帶電體與帶電體之間、帶電體與人體之間、帶電體與其他設施和設備之間,均應保持一定距離。通常,在配電線路和變、配電裝置附近工作時,應考慮線路安全距離,變、配電裝置安全距離,檢修安全距離和操作安全距離等。
(3) 安全載流量。導體的安全載流量,是指允許持續通過導體內部的電流量。持續通過導體的電流如果超過安全載流量,導體的發熱將超過允許值,導致絕緣損壞,甚至引起漏電和發生火災。因此,根據導體的安全載流量確定導體截面和選擇設備是十分重要的。 (4) 標志。明顯、准確、統一的標志是保證用電安全的重要因素。標志一般有顏色標志、標示牌標志和型號標志等。顏色標示表示不同性質、不同用途的導線;標示牌標志一般作為危險場所的標志;型號標志作為設備特殊結構的標志。
四、 安全技術方面對電氣設備基本要求
電氣事故統計資料表明,由於電氣設備的結構有缺陷,安裝質量不佳,不能滿足安全要求而造成的事故所佔比例很大。因此,為了確保人身和設備安全,在安全技術方面對電氣設備有以下要求: (1) 對裸露於地面和人身容易觸及的帶電設備,應採取可靠的防護措施。
(2) 設備的帶電部分與地面及其他帶電部分應保持一定的安全距離。
(3) 易產生過電壓的電力系統,應有避雷針、避雷線、避雷器、保護間隙等過程電壓保護裝置。
(4) 低壓電力系統應有接地、接零保護裝置。
(5) 對各種高壓用電設備應採取裝設高壓熔斷器和斷路器等不同類型的保護措施;對低壓用電設備應採用相應的低電器保護措施進行保護。
(6) 在電氣設備的安裝地點應設安全標志。
(7) 根據某些電氣設備的特性和要求,應採取特殊的安全措施。
五、 電氣事故的分類及基本原因的分類 電氣事故按發生災害的形式,可以分為人身事故、設備事故、電氣火災和爆炸事故等;按發生事故時的電路狀況,可以分為短路事故、斷線事故、接地事故、漏電事故等;按事故的嚴重性,可以分為特大性事故、重大事故、一般事故等;按傷害的程度,可以分為死亡、重傷、輕傷三種。

特區建設和應用的機器
機器的特區建設
一個特區機器是由兩個基本的組成部分:
——這是靜止不動的部分定子的機器。它由下列內容:軛加在一個框架;激勵;極點和繞組compoles交換桿()和繞組;最後盾牌球或滑動軸承,刷子和刷子持有人;端子箱。
-轉子是感人的部分的機器。它是由一個核心安裝在機器軸上。這個核心有均勻的間隔槽電樞繞組所擬合。一個換向器,經常是一種球迷,也位於機軸上。
訊框會被固定在地板上,通過一個台板、螺栓。在低功率的機器框架和軛架是同一個組件,通過它把磁鏈所產生的勵磁磁極關閉。架構以及建造的軛是鑄鐵或鑄鋼或有時因焊接鋼板。
rectifier-supplied中的低功率和控制的機器的軛是建立(0.5 ~等級)層鐵皮。因為我的軛是通常的被裝進一個non-ferromagnetic框架(通常由alumininum合金、保持體重減下來)。對任何一方的框架有螺栓兩端蓋,其中蘊含的球或滑動軸承。
(主)激勵的撐桿從0.5 ~等級的鐵皮抱著鉚接螺栓。兩極是固定在一個畫面上通過螺栓。他們支持這個繞組勵磁電流攜帶著。
結果表明,在轉子彎曲故障的一面,最後撐竿的核心就是所謂的pole-shoe意思是促進一個給定的分布,通過氣隙磁通。彎彎曲曲的,在裡面放上一個隔離框架安裝在核心,並提前清償所擔保的pole-shoe。
勵磁繞組的是由絕緣的圓形或矩形導體,連接不管是串聯或並聯。各繞組之間是有聯系的,在這種情況下磁通的一桿穿過空氣間隙的pole-shoe是直接來自於對電樞(北極),膜通量的下一個桿都直接受電樞的pole-shoe(南極)。
