Fig. 2 is the connecting base structure schematic diagram of the present invention；
Fig. 3 is the electric control theory figure of the present invention.
Embodiment
The embodiment of the present invention is further described below in conjunction with accompanying drawing.
A kind of device for being used to supervise Existing during Partial Discharge Test for Transformer quality, as shown in Figures 1 and 2, by transverse arm 1, side arm
2nd, connecting seat 4 and control are formed with display box 3.Described two side arms are perpendicularly fixedly arranged on transverse arm both ends, and the side arm and transverse arm are equal
For hollow structure, the connecting seat and control are arranged on side arm with inside transverse arm, dividing in two lower ends of connecting seat with display box
Metal sheeting 6 is not provided with by holddown spring 5, connecting seat promotes metal sheeting by holddown spring, so as to and transformer terminal
Son keeps good contact, is reliably connected so as to realize with transformer terminal.The preceding surface in transverse arm center is provided with indicator lamp
L, S and debugging button BS are switched and is connected with controlling with the control inside display box with display circuit, indicator lamp L is used to refer to
Show whether experiment normally completes, switch S is used for the break-make of control device power supply, and debugging button BS is used in preoperation inspection
Whether the situation of device is good.
The electric control principle of the present invention as shown in figure 3, be packaged with two capacitors C1 and C2, in horizontal stroke respectively in two side arms
Capacitor C3 is packaged with arm, capacitor C1, C2, C3 are connected in series, and are parallel with relay R at capacitor C3 both ends, the relay
Device R controls a normally opened contact Ra.Control and display circuit, the control and display circuit bag are installed in control with display box
Relay TLR and two normally opened contact TLRa1 and TLRa2 is included, relay TLR is deferred action relay and control two
Normally opened contact TLRa1 and TLRa2.After normally opened contact Ra is in parallel with normally opened contact TLRa1, connected with relay TLR.Normally opened contact
After TLRa2 is in parallel with debugging button BS, connected with indicator lamp L.Switch S connects with dc source E.
The present invention application method be：
(1) test parameters is set：When voltage-duration in partial discharge test is arranged into relay TLR delay
Between.
(2) close a switch S, presses debugging button BS, checks whether indicator lamp L is working properly.If press button bright light,
Release button lamp goes out, and illustrates device in order.
(3) by present apparatus installation on the transformer, it is made to be reliably connected with transformer terminal.Start partial discharge of transformer
Experiment：
1. when test voltage reaches defined magnitude of voltage, relay R actions, normally opened contact Ra closures；
2. in the delay time of relay TLR settings, if test voltage does not reduce, normally opened contact Ra will be protected always
Hold closure state；
3. after the delay time of setting, relay TLR actions, normally opened contact TLRa1 and TLRa2 closure；
4. indicator lamp L is lighted, illustrate that test voltage and test period are satisfied by defined requirement；
5. test voltage lands, relay R resets, and normally opened contact Ra disconnects；
6. because TLRa1 is closed, relay TLR still keeps operating state, and indicator lamp L is persistently lighted.
(4) partial discharge test terminates, and supervisor removes device and checks LED status.If it is indicated that lamp is bright, say
Bright experiment is carried out in accordance with regulations, if it is indicated that lamp is not bright, illustrates that experiment is not reaching to related request.
(5) switch S is opened, experiment supervision work terminates.
It is emphasized that embodiment of the present invention is illustrative, rather than it is limited, therefore the present invention is simultaneously
The embodiment described in embodiment is not limited to, it is every to be drawn by those skilled in the art's technique according to the invention scheme
Other embodiment, also belong to the scope of protection of the invention.
