Abstract
The utility model discloses a kind of close to closing detecting apparatus, it is characterised in that include the devices such as 24V D.C. regulated power supplies, breaker, DC voltage display table, can effectively detect the quality close to switch, it can and can be convenient and efficient.
Description
Technical field
The utility model is related to arrive a kind of detection device more particularly to a kind of close to closing detecting apparatus, belong to electrical
Apparatus field.
Background technology
It is very extensive in the use of every field close to switch, and brand and model is also very much, but due to close switch
Operation principle, all close switches are broken down using metal all-closed encapsulation, therefore when close to switch internal mechanism
When, we can not intuitively have found, it is therefore desirable to a kind of effectively to detect the device close to switch quality to judge.
Invention content
The utility model provides a kind of can effectively detect close to the fine or not device of switch, and can be convenient and efficient.
The technical solution of the utility model is：
It is a kind of to include close to switch close to closing detecting apparatus, it is described to include close to switch close to switch anode
End, close to switch negative pole end, close to switching voltage signal output terminal, it is characterised in that also include 24V D.C. regulated power supplies, disconnected
Road device, DC voltage show table, and the 24V D.C. regulated power supplies include power positive end and power cathode end, described
DC voltage display table includes voltmeter positive terminal, voltmeter negative pole end and voltmeter voltage signal inputs, the electricity
Source positive terminal is connect with close to switch positive terminal by electric wire, and the voltmeter positive terminal is connected to positive pole by electric wire
On electric wire between end and close switch positive terminal, the breaker is installed on voltmeter positive terminal and close switch positive terminal
Electric wire tie point and power positive end between electric wire on, the power cathode end passes through electric wire and voltmeter negative pole end phase
Even, described to be connected on the electric wire between power cathode end and voltmeter negative pole end by electric wire close to switch negative pole end, institute
The voltmeter voltage signal inputs stated are connected by electric wire with close to switching voltage signal output terminal.
Description of the drawings
Fig. 1 is a kind of structure diagram close to closing detecting apparatus.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It is as shown in Figure 1 a kind of close to closing detecting apparatus, include close to switch 4, it is described to include close to switch 4
Close to switch positive terminal 41, close to switch negative pole end 43, close to switching voltage signal output terminal 42, it is characterised in that also include
24V D.C. regulated power supplies 1, breaker 2, DC voltage show table 3, and the 24V D.C. regulated power supplies 1 include positive pole
End 11 and power cathode end 12, the DC voltage display table 3 include voltmeter positive terminal 31,32 and of voltmeter negative pole end
Voltmeter voltage signal inputs 33, the power positive end 11 is connect with close to switch positive terminal 41 by electric wire, described
Voltmeter positive terminal 31 by electric wire be connected to power positive end 11 and close to switch positive terminal 41 between electric wire on, it is described
Breaker 2 be installed on voltmeter positive terminal 31 and close to switch the electric wire tie point of positive terminal 41 and power positive end 11 between
Electric wire on, the power cathode end 12 is connected by electric wire with voltmeter negative pole end 32, described close to switch negative pole end
43 are connected to by electric wire on the electric wire between power cathode end 12 and voltmeter negative pole end 32, the voltmeter voltage signal
Input terminal 33 is connected by electric wire with close to switching voltage signal output terminal 42.
Operation principle：When the breaker 2 is connected, it is detected close to switch 4 and obtains 24V DC power supplies, direct current
Voltage display table 3 obtains 24V DC power supplies, when it is intact to be detected close switch 4, is detected connecing close to switch 4
Nearly switching voltage signal output terminal 42 has the output of 24V d. c. voltage signals, and 24V d. c. voltage signals are input to DC voltage
Show the voltmeter voltage signal inputs 33 of table 3, DC voltage shows that table 3 shows 24V DC voltages, therefore we can at this time
Judge that detected close switch 4 is intact with intuitive.When faulty close switch 4 or damage is detected, it is detected and connects
Nearly switch 4 is less than 24V, and DC voltage close to switching voltage signal output terminal 42 without signal voltage output or output voltage
The voltage value of voltage value or display less than 24V will not be shown on display table 3, therefore we equally can intuitively judge to be detected
Close to 4 damage of switch.The method can simply, efficiently detect to approach the quality of switch 4.
When the utility model combination above example is come when illustrating, those skilled in the art should be noted that can be with
Various change is carried out to the utility model and component is replaced.Accordingly, it is to be understood that：The utility model is not limited only to here
The specific embodiment of disclosed optimal mode implements the utility model.Under the premise of conceiving without departing substantially from the utility model, institute
It changes and is each fallen in the protection domain of appended claims with modification.
