Specifically: [ 1913 Webster PJC] ( a) A quantity of explosives anchored in a channel, beneath the water, or set adrift in a current, and so designed that they will explode when touched or approached by a vessel, or when an electric circuit is closed by an operator on shore; now called { marine mine}. [ obsolete] [ 1913 Webster PJC] Damn the torpedoes -- full speed ahead! -- Adm. David Glasgow Farragut ( At the battle of Mobile Bay, 1864). ( b) A kind of small submarine boat carrying an explosive charge, and projected from a ship against another ship at a distance, or made self- propelling, and otherwise automatic in its action against a distant ship. [ 1913 Webster] 3. ( Mil.) A kind of shell or cartridge buried in earth, to be exploded by electricity or by stepping on it; now called { land mine}. [ obsolete] [ 1913 Webster PJC] 4. ( Railroad) A kind of detonating cartridge or shell placed on a rail, and exploded when crushed under the locomotive wheels, -- used as an alarm signal. [ 1913 Webster] 5. An explosive cartridge or shell lowered or dropped into a bored oil well, and there exploded, to clear the well of obstructions or to open communication with a source of supply of oil. [ 1913 Webster] 6. A kind of firework in the form of a small ball, or pellet, which explodes when thrown upon a hard object. [ 1913 Webster] 7. An automobile with a { torpedo body}. [ Archaic Cant] [ Webster 1913 Suppl. PJC] { Fish torpedo}, a spindle- shaped, or fish- shaped, self- propelling submarine torpedo. { Spar torpedo}, a canister or other vessel containing an explosive charge, and attached to the end of a long spar which projects from a ship or boat and is thrust against an enemy' s ship, exploding the torpedo. { Torpedo boat}, a vessel adapted for carrying, launching, operating, or otherwise making use of, torpedoes against an enemy' s ship., especially, a small, fast boat with tubes for launching torpedoes. { Torpedo nettings}, nettings made of chains or bars, which can be suspended around a vessel and allowed to sink beneath the surface of the water, as a protection against torpedoes. [ 1913 Webster]
Crampfish \ Cramp" fish`\ ( kr? mp" f? sh`), n. ( Zool.) The torpedo, or electric ray, the touch of which gives an electric shock. See { Electric fish}, and { Torpedo}. [ 1913 Webster]

- 低压验电器可以检出500v以下的电压为什么是错的?_百度知道
总结来说,低压验电器是专为低电压设计的设备,无法准确检测高电压。 因此,它不能用于检测500v以上的电压,更不用说检测出500v以下的电压了。 在实际应用中应当注意其适用范围和使用安全。
- 低压验电器可以检出500v以下的电压为什么是错的_百度知道
低压验电器可以检出500v以下的电压为什么是错的低压验电器是用来检验对地电压在1000V及以下的低压电气设备的,也是家庭中常用的电工安全工具。它主要由工作触头、降压电阻、氖泡、弹簧等部件组成。这种验电器它是利
- 低压验电器可以验出500伏以下的电压_百度问一问 - Baidu
错误。 因为普通低压验电器(测电笔)只可以验出60V~500V的电压,低于60V电压是无法检出的。 使用低压验电器时应注意的事项如下: 1、测量前应先检查低压验电器是否完好,在确定有电的导体进行测试,证实低压验电器可发光或显示数字, 2、使用低压验电器一般应穿绝缘鞋,同时不握低压验电器
- 低压验电器可以检出500v以下的电压为什么是错的_百度知道
所以,认为低压验电器可以检出500V以下电压的说法是错误的。 详细解释: 低压验电器设计的初衷是为了在电力系统中保证人员的安全,主要针对对地电压在特定的范围内的设备进行验电操作。 这种设备的工作原理决定了其只能适用于低电压环境。
- 低压验电器可以检出500v以下的电压为什么是错的?
普通低压验电器(测电笔)可以验出60V~500V的电压,低于60V电压是无法检出的。一般在带电体与大地间的电位差低于36V,氖泡不发光,在60V~500V的电压时氖泡发光,电压越高氖泡越亮。当测试电压范围在6V~24V之间时,人们常常使用弱电验电笔。 扩展资料: 验电笔除能测量物体是否带电的功能外,还有
- 低压验电器可以验出500v以下的电压_百度问一问 - Baidu
总之,低压验电器可以有效地测试出500V以下的电压,提高了对低压电线或设备的安全性的把控。 但在使用低压验电器进行测试的同时,也应该遵循正确的操作方法,并尽可能地采取预防措施,以确保测试的准确性和安全。
- 求问低压验电器可以验出500v以下的电压为什么是错的_百度知道
避免在超出其设计范围的电压下使用,以免造成不必要的损失和风险。 因此,认为低压验电器可以验出500V以下的电压是错误的,这可能导致误操作和安全事故的发生。 在使用验电器之前,务必明确其额定电压范围和使用条件,确保在安全范围内进行操作。
- 低压验电器可以验出500v以下的电压是正确的吗_百度知道
低压验电器俗称测电笔,它是用来检验对地电压在250V及以下低压电气设备的工具,也就是说它最高能检测出250V的电压。 因此,“低压验电器可以验出500v以下的电压”这一说法不是完全正确的。 低压验电器主要由工作触头、降压电阻、氖泡、弹簧等部件组成。
- 低压验电器可以检出500v以下的电压为什么是错的
低压验电器可以检出500v以下的电压为什么是错的?因为普通低压验电器 (测电笔)只可以验出60V~500V的电压,低于60V电压是无法检出的。 试电笔中笔尖、笔尾、为金属材料制成,笔杆为绝缘材料制成。 使用试电笔时,一定要用手触及试电笔尾端的金属部分,否则,因带电体、试电笔、人体与大地没有
