Abstract
The invention discloses a zero line and live line detection module which is capable of quickly detecting phase of a zero line and a live line of a power line connected with the module, simple in structure and operation, high in practicability and capable of effectively prolonging service life of electric appliances connected with the module or effectively protecting the electric appliances and preventing the electric appliances from being burnt due to phase error of the connected power line.
Description
Technical field
The present invention relates to a kind of detection module, specifically a kind of detection module for detecting zero live wire phasic property.
Background technology
At present; the zero line and the live wire that all need closely to distinguish the access power lead when external power supply of a lot of electric equipments accesses on the market; in case connecing little, zero line and live wire shorten serviceable life of equipment; heavy then whole electric equipment is burnt; at present all be that protection coil at live wire and zero line outer wrapping different colours is to show differentiation; after but many times production is finished; can't distinguish live wire and zero line from access; this just must be constructed by the technical professional; consumption manpower consuming time, and use inconvenient.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, a kind of detection module that can detect zero live wire phasic property is provided.
Technical scheme: in order to realize above purpose, a kind of zero live wire detection module of the present invention comprises: neon tube, photoresistance, pull-up resistor R1 and pull-up resistor R3; Neon tube is relative with photoresistance, and is positioned at confined space, connects in external power supply after the neon tube one end series load resistance R 1, and the other end is connected with tank shell, tank shell ground connection; Be connected with power supply after the photoresistance one end series load resistance R 3, the other end is connected with the heating tube gauge tap.
When the present invention worked, when the tested power lead that is connected with neon tube was live wire, it is after-applied in the neon tube two ends that AC power is connected 1 step-down of overload resistance R, neon tube is luminous, because neon tube and photoresistance are positioned at confined space, when neon tube is luminous, the photoresistance resistance descends, and output voltage descends; When the tested power lead that is connected with neon tube was zero line, then neon tube two ends electric potential difference was zero, can't excite neon tube luminous, and the photoresistance resistance is constant.
Zero live wire detection module of the present invention; can correctly judge the phasic property of the zero live wire of access power lead; guaranteed that the electric equipment access power lead zero live wire phasic property that links to each other with zero live wire detection module is correct; prolonged the serviceable life of equipment; or effectively protected electric equipment, do not cause burning because of access power lead phasic property mistake.
Can also comprise in the zero live wire detection module described in the present invention: warning device, described warning device links to each other with an end of photoresistance.The user can set warning device as required, is the live wire alarm if need to judge the access power lead, only needs to set, and when output voltage descended, warning device was reported to the police; When output voltage was constant, warning device was not reported to the police.Otherwise opposite the setting gets final product.
Beneficial effect: zero live wire detection module of the present invention has the following advantages:
Zero live wire detection module of the present invention can detect the phasic property of the zero live wire of the power lead that is attached thereto fast; simple in structure; practicality is high; can effectively prolong the serviceable life of the electric equipment that is attached thereto; or effectively protected electric equipment, do not cause burning because of access power lead phasic property mistake.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
Embodiment
A kind of zero live wire detection module as shown in Figure 1 comprises: warning device, neon tube, photoresistance, pull-up resistor R1 and pull-up resistor R3; Neon tube is relative with photoresistance, and is positioned at confined space, connects in external power supply after the neon tube one end series load resistance R 1, and the other end is connected with tank shell, tank shell ground connection; Be connected with power supply after the photoresistance one end series load resistance R 3, the other end is output terminal, is connected with warning device.
The present embodiment course of work is as follows:
When zero live wire detection module detects the circumscripted power line that is attached thereto and is live wire, neon tube in the zero live wire detection module is luminous, because neon tube and photoresistance are positioned at confined space, when neon tube is luminous, the photoresistance resistance descends, output voltage descends, and alarm activation is reported to the police, and reminds the zero live wire order that changes external power supply; When zero live wire detection module detected the power lead that is attached thereto and is zero line, then neon tube two ends electric potential difference was zero, can't excite neon tube luminous, the photoresistance resistance is constant, output voltage is constant, when zero live wire detection module output voltage is constant, and the electric equipment normal operation that is attached thereto.
Claims (2)
1. zero a live wire detection module is characterized in that: comprising: neon tube, photoresistance, pull-up resistor R1 and pull-up resistor R3; Neon tube is relative with photoresistance, and is positioned at confined space, connects other end ground connection in external power supply after the neon tube one end series load resistance R 1; Be connected with power supply after the photoresistance one end series load resistance R 3, the other end is output terminal;
When the tested power lead that is connected with neon tube was live wire, it is after-applied in the neon tube two ends that AC power is connected 1 step-down of overload resistance R, and neon tube is luminous, because neon tube and photoresistance are positioned at confined space, when neon tube was luminous, the photoresistance resistance descended, and output voltage descends; When the tested power lead that is connected with neon tube was zero line, then neon tube two ends electric potential difference was zero, can't excite neon tube luminous, and the photoresistance resistance is constant, and output voltage is constant.
2. a kind of zero live wire detection module according to claim 1, it is characterized in that: comprise in the described zero live wire detection module: warning device, described warning device links to each other with an end of photoresistance.
