Description
一种可检测外部漏电电压的插座 技术领域 Socket capable of detecting external leakage voltage
[0001] 本发明涉及用于检测观赏类水生动物养殖器具外部电压的一种可检测外部漏电 电压的插座。 [0001] The present invention relates to a socket for detecting an external leakage voltage for detecting an external voltage of an ornamental aquatic animal culture apparatus.
背景技术 Background technique
[0002] 当前的家用电源连接的排插或可检测外部漏电电压的插座中, 不少仅配备简单 的幵关功能或过载保护功能, 保护功能较单一; 有的可检测故障电弧的功能, 可以检测当可检测外部漏电电压的插座接触不良吋所引发的故障电弧, 并自动 切断电源。 然而, 实际使用场景中还有一种情况: 当电源可检测外部漏电电压 的插座或排插其自身或其负载产生漏电吋, 由于没有接地或没有与人接触, 从 而没有形成回路, 不产生电流, 更不产生电弧。 上述的现存的电源连接产品中 , 都无法检测此种漏电情况, 在发生该状况吋无法关断电源, 从而可能引起触 电事故。 [0002] In the current sockets for household power connection or sockets that can detect external leakage voltage, many of them are only equipped with simple shut-off function or overload protection function, and the protection function is relatively simple; some can detect the fault arc function, Detects a fault arc caused by poor contact of the socket that can detect the external leakage voltage, and automatically cuts off the power. However, there is another case in the actual use scenario: When the power supply can detect the external leakage voltage of the socket or the plug or the load or the load generates the leakage 吋, since there is no grounding or no contact with the human, no loop is formed and no current is generated. No more arcing. In the above existing power connection products, such leakage cannot be detected. When this condition occurs, the power cannot be turned off, which may cause an electric shock.
[0003] 而最为典型的就是潜水产品, 例如家庭养观赏鱼的潜水泵、 加热棒等设备, 由 于设备的密封性不好导致入水, 进而产生漏电, 由于家庭通常用绝缘玻璃制鱼 缸来养鱼, 产生的漏电没有形成回路, 不产生漏电电流, 观赏鱼处于有电压、 无电流的带电的水中正常游动, 当人在不知情的情况下触摸到鱼缸里面的水, 这吋水、 人和大地形成了回路, 使人和鱼体内都有电流通过而造成伤害。 [0003] The most typical ones are diving products, such as submersible pumps for household aquarium fish, heating rods, etc., due to the poor sealing of the equipment, which causes water to enter, which causes leakage. Because the family usually uses insulated glass fish tanks to raise fish, The generated leakage does not form a loop, does not generate leakage current, and the ornamental fish swims normally in the charged water with voltage and no current. When the person touches the water inside the fish tank without knowing, the water, the human and the earth are formed. The circuit causes the current and the body of the fish to pass through and cause damage.
[0004] 另外, 当电源可检测外部漏电电压的插座或排插其自身或其负载产生漏电, 虽 然产生了回路形成了电流, 当由于电流比较微弱, 不至于触发漏电保护幵关进 行关断电源, 而这种漏电会对人带来一定的危害。 而目前已公幵的电源连接的 产品中, 对以上的无回路漏电和有回路的微弱电流的漏电引起的问题达不到有 效的解决。 [0004] In addition, when the power supply can detect the external leakage voltage of the socket or the socket or its load generates leakage, although the loop generates a current, when the current is weak, the leakage protection is not triggered to turn off the power. And such leakage will bring certain harm to people. In the products of the currently announced power connection, the problems caused by the above leakage of no loop leakage and leakage of weak current with a loop are not effectively solved.
