Description

A kind of oscillograph of isolation power supply

Technical field

This utility model is related to oscillograph, particularly a kind of oscillograph of isolation power supply.

Background technology

As oscillograph is to adopt mains-supplied, if test interface is accessed civil power or non-isolated driver is tested When, civil power can be brought into inside oscillograph with oscillograph for electric forming pressure reduction, gently then cause city's electric tripping in whole room to protect Shield, it is heavy then damage oscillograph, but the driving of non-isolated is increasingly cumulative in the market, and oscillograph can not be tested to which and very Passively.

Utility model content

To solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of oscillograph of isolation power supply.

The technical solution adopted in the utility model is：

A kind of oscillograph of isolation power supply, including the isolating transformer, oscillograph body that sequentially access from civil power, the oscillography The test port of device body is used to connect isolation target to be tested or non-isolated target.

The oscillograph body includes oscillograph shell, support feet and handle, and the oscillograph case nose face is provided with little Display screen and control panel, oscillograph rear end face centre position are provided with big display screen, and oscillograph outer casing top surface is provided with parcel tray, There is slip lid on parcel tray, in parcel tray, be provided with division board, parcel tray is divided into two parts of size, is set in big part by division board There is convex rod, convex rod is isolated in the separate big part of plate in parcel tray and is uniformly distributed, the handle two ends and oscillograph shell Top surface is fixedly connected, and oscillograph side is provided with baffle plate, and the support feet is arranged at the corner of oscillograph bottom surface.

The big display screen surface is provided with wear-resisting grid coating.

The handle length is more than parcel tray length, and handle is highly more than parcel tray height.

The baffle plate inward at both ends depression.

The support feet bottom is provided with anti-slip rubber set.

The beneficial effects of the utility model：

This utility model is started with from oscillographic operation principle, and oscillographic power supply is opened with mains isolation, has both realized supplying Electricity, realizes isolation again, so that oscillograph easily faces the measurement that the measurement of civil power and non-isolated drive.

Description of the drawings

Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.

Fig. 1 is the oscillographic schematic diagram of this utility model.

Fig. 2 is the oscillographic structural representation of this utility model；

Specific embodiment

With reference to shown in Fig. 1, be it is of the present utility model it is a kind of isolation power supply oscillograph, including sequentially access from civil power every From transformator, oscillograph body, the test port of the oscillograph body is used to connect isolation target to be tested or non-isolated target. This utility model is started with from oscillographic operation principle, oscillographic power supply is opened with mains isolation, power supply has both been realized, is realized again Isolation, so that oscillograph easily faces the measurement that the measurement of civil power and non-isolated drive.

As shown in Fig. 2, Fig. 3 and Fig. 4, oscillograph body of the present utility model includes oscillograph shell 1, support feet 9 and carries Handss 5,1 front end face of oscillograph shell are provided with small display 2 and control panel 3, and oscillograph rear end face centre position is provided with Big display screen 4,1 top surface of oscillograph shell are provided with parcel tray 6, have the electronic devices such as slip lid 7, wire be placed on parcel tray 6 In parcel tray 6, the control parcel tray 6 of slip lid 7 is opened and is closed, and is provided with division board 12 in parcel tray 6, and division board 12 is by parcel tray 6 It is divided into two parts of size, in big part, is provided with convex rod 13, convex rod 13 is isolated the separate big part of plate 12 in parcel tray 6 Inside it is uniformly distributed, wire is placed in parcel tray and will not be separately intertwined by convex rod 13, outside 5 two ends of the handle and oscillograph 1 top surface of shell is fixedly connected, and oscillograph side is provided with baffle plate 8, and the support feet 9 is arranged at the corner of oscillograph bottom surface.

It should be noted that having wear-resisting grid coating 11 on big display screen 4, scale can be put on and facilitate reading；Handle 5 is grown Degree makes handle 5 and parcel tray 6 mutually not disturb more than parcel tray height 6 more than 6 length of parcel tray, 5 height of handle；8 liang of baffle plate End caves inward so that CRO coupling can be wrapped on baffle plate 8；9 bottom of support feet be provided with anti-slip rubber set 10, can in case Only oscillograph slides.

Summary, the oscillograph body have two display screens, facilitate many people while observing waveform, also have on big display screen Wear-resisting grid coating, can put on scale and facilitate reading, CRO coupling be wrapped on side board, the electronics device such as wire Part can be placed in parcel tray, have slip lid control parcel tray to open and close on parcel tray, and oscillograph housing top end has handle side There is anti-slip rubber set under Portable belt, support feet, prevent oscillograph from sliding.

Preferred embodiments of the present utility model are the foregoing is only, this utility model is not limited to above-mentioned embodiment party Formula, if with essentially identical means realize the technical scheme of this utility model purpose belong to protection domain of the present utility model it It is interior.
