Description
Technical field
The utility model belongs to technical field of automation in industry, particularly relates to a kind of relay contacts resistance on-Line Monitor Device.
Background technology
Existing monitoring device, its coil is contained on " U " shape magnetic conductor, has the armature that one movable above magnetic conductor, and two bank contact shell fragments are equipped with in magnetic conductor both sides.At non-action status lower contact shell fragment, armature is upwards held up, make to keep certain interval between armature and magnetic conductor.When electromagnetic torque when between air gap exceedes the moment of reaction, armature is attracted to magnetic conductor, and armature presses contact shell fragment simultaneously, makes normally closed contact disconnect normally opened contact and closes, complete relay work.When electromagnetic torque is reduced to certain value, due to the moment of reaction of contact shell fragment, and make contact and armature turn back to initial position, prepare lower task.
" U " shape magnetic conductor of this relay adopts two core construction, namely on two side columns, all can install coil.A coil is only filled for DZY, DZL and DZJ type, and can fill with holding coil or time delay damping fin etc. on another iron core as required for DZB, DZS, DZK type.Thus all general magnetic conductor of the relay that coil-type is differed widely.
Above-mentioned present technology existing problems are: when relay " U " shape conductor cannot fully contact with its moving armature, can cause whole relay scaling loss, or produce harmful effect because relay contacts is bad to equipment.
Utility model content
The utility model, for above-mentioned prior art Problems existing, provides a kind of relay contacts resistance on-Line Monitor Device, its objective is to provide a kind of new relay and relay working condition in-service monitoring device.Both with the use of, can when relay works, the contact resistance between " U " property conductor of on-line monitoring relay and armature.When contact resistance is excessive, display power transfer relay is also reported to the police.
The utility model is achieved through the following technical solutions:
Relay contacts resistance on-Line Monitor Device, comprises relay.Be connected with relay by the cross beam frame arranged in it by monitoring device; Feeler row on monitoring device base are all connected external direct current power supply with feeler row, and the loop of external direct current power supply is provided with pilot lamp.
Described cross beam frame is plug in construction, and namely monitoring device is provided with socket, and relay is provided with the plug-in unit matched with the socket on monitoring device.
Described monitoring device is provided with single or multiple being set up in parallel.
Advantage of the present utility model and good effect as follows:
When monitored excessive to direct current resistance time, this device of utility model can show power transfer relay, and reports to the police.Can serviceable life of effective control relay, remind staff to change old relay in time; Also can directly reflect relay fault, facilitate fault discovery during accident treatment.Significantly improve the Personal Safety of electric system hot line job personnel, greatly reduce the accident rate of hot line job.Electric system can be widely applicable for.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is side-looking structural representation of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is cut-away drawing of the present utility model.
In figure: feeler row 1, feeler row 2, pilot lamp 3, external direct current power supply 4, cross beam frame 5.
Embodiment
The utility model is a kind of relay contacts resistance on-Line Monitor Device.As Figure 1-3.
On-Line Monitor Device is a kind of novel relay base, as shown in Figure 1.Its contour structures and common relay socket similar, can be single also can be side by side multiple, Fig. 2 is multiple embodiments arranged side by side.Difference the feeler row 1 of this base and feeler row 2 adds external direct current power supply 4 to carry out electricity the moon and measure, and monitor DC loop adding a run indicator 3, and its wiring as shown in Figure 3.Node or a row close node is opened herein for row, the situation that other situations all exist as opening and closing node, analogize as benchmark, function for monitoring is completed by a pilot lamp 3, namely when node contact is good, monitoring circuit conducting, pilot lamp is bright: when contacting bad, monitoring circuit resistance becomes large, and instruction etc. cannot normally work.Therefore, this device when relay a pair node virtual connection or broken string, can reflect its state.
General relay is all stuck on the cross beam frame in cabinet, and the utility model is that the cross beam frame 5 in cabinet is designed to plug in construction, is inserted in the utility model relay on-Line Monitor Device by relay by plug-in type cross beam frame.That is: in relay on-Line Monitor Device, be provided with socket, relay is provided with the plug-in unit matched with the socket in relay on-Line Monitor Device.During enforcement, first the plug-in unit on relay is inserted in the socket in relay on-Line Monitor Device.
Now the utility model relay on-Line Monitor Device both can fixed relay, for relay provides operating voltage, can also play the effect ruuning situation of relay being made to on-line monitoring.
Principle is sketched: on " U " shape conductor of relay, increase by a road external direct current power supply, feeler row 1 namely in Fig. 2 and between feeler row 2, and this external direct current power supply is provided by on-Line Monitor Device, by relay excitation current trigger.That is, when this relay excitation, just meeting on-Line Monitor Device can at relay " U " shape conductor Shang Jia mono-road direct current.On-Line Monitor Device plays the effect of instrument for measuring DC resistance, can carry out real-time straight resistance measure monitored relay.
When monitored excessive to direct current resistance time, the charged pilot lamp of this device extinguishes because operating voltage diminishes, and can find out malfunctioning node intuitively.This device can serviceable life of effective control relay, reminds staff to change old relay in time; Also can directly reflect relay fault, facilitate fault discovery during accident treatment.
