The utility model relates to a standby power consumption testing capability verification sample, which comprises a high temperature resistant waterproof insulation casing and a standard circuit module. The standby power consumption testing capability verification sample is characterized in that he standard circuit module is fixed inside the high temperature resistant waterproof insulation casing, two sides of the high temperature resistant waterproof insulation casing are respectively connected with a power switch, a power input end and an electrical parameter output end, a mode changing switch and a mode indication light-emitting diode (LED) lamp are installed on the surface of the high temperature resistant waterproof insulation casing, the standard circuit module is connected with the power input end through the power switch and composed of a standard circuit and a compensation circuit, the mode changing switch selects to be connected with the corresponding standard circuit and compensation circuit in the standard circuit module, and the corresponding nominal mode indication light-emitting diode lamp is conducted. The standard sample serves as a sample, a problem of sample applicability is solved, sample power and input power supplies can be selected, simultaneously the sample passes through uniformity and stability inspection and is proved that performance meets requirements of performance testing samples through actual use of performance testing of China conformity assessment national accreditation service on a nation wide scale.

Description

A kind of stand-by power consumption power of test verification sample

Technical field

The utility model relates to a kind of electrical detection facility, particularly a kind of stand-by power consumption power of test verification sample.

Background technology

The electrical field is that CNAS is to one of breadboard approval field; Proficiency testing is evaluation and supervises one of important means of mechanism's technical capabilities such as detection, calibration, inspection; Also being a kind of effective external mass assurance activity, is replenishing of its internal soundness control technology.

Stand-by power consumption test is basis, the core project that the electric field efficiency detects, be product efficiencies such as household electrical appliances, info class equipment, audio & video equipment and power supply adaptor detect must survey project.All there are Compulsory Feature in China, European Union and the U.S. to the stand-by power consumption of product.It adopts the average power method to survey stand-by power consumption, promptly passes through to measure the power consumption of sample in a period of time, thereby obtains the method for the average power of sample.

Because the structure of electric product varies, with respect to fields such as chemical solution, starting material, the product structure relative complex, the sample difficulty that obtain homogeneity and good stability is bigger, and manufacturing cost is higher.It is again the emerging test item of electric field that efficiency detects.At present, no matter be the world or domestic, all there is not other to organize the checking of stand-by power consumption power of test.

Summary of the invention

The utility model is the big problem of sample difficulty that obtains homogeneity and good stability to the electrical field; A kind of stand-by power consumption power of test verification sample has been proposed; When making the stand-by power consumption power of test checking of sample in electric efficiency detection range have versatility, guaranteed the homogeneity and stability of sample.

The technical scheme of the utility model is: a kind of stand-by power consumption power of test verification sample; Comprise high temperature resistant waterproof insulation crust, preferred circuit module; It is characterized in that; It is inner that said preferred circuit module is fixed in the high temperature resistant waterproof insulation crust, and high temperature resistant waterproof insulation crust both sides are connected to power switch, power input, electrical quantity output terminal respectively, and high temperature resistant waterproof insulation crust mounted on surface has mode selector switch and pattern indication LED lamp; The preferred circuit module is connected with power input through power switch; The preferred circuit module is made up of preferred circuit and compensating circuit, and mode selector switch selects to connect preferred circuit corresponding in the preferred circuit module, compensating circuit connects, corresponding pattern indication LED lamp conducting of demarcating.

Said preferred circuit and compensating circuit all adopt distributed wiring.

The beneficial effect of the utility model is: the utility model stand-by power consumption power of test verification sample; Solved the problem of sample applicability as sample with this standard model; Sample power, input power supply can be selected; The while sample is through homogeneity and stability test, and process CNAS proves that in the actual use of nationwide proficiency testing its performance meets the requirement of proficiency testing sample.

Description of drawings

Fig. 1 is the utility model stand-by power consumption power of test verification sample structural representation.

Embodiment

Stand-by power consumption power of test verification sample structural representation as shown in Figure 1 comprises high temperature resistant waterproof insulation crust 1, preferred circuit module 7, in the said high temperature resistant waterproof insulation crust 1 preferred circuit module 7 is arranged, and is fixed in high temperature resistant waterproof insulation crust 1.

High temperature resistant waterproof insulation crust 1 both sides are connected to power switch 2, power input 3, electrical

quantity output terminal

5,6 respectively, and high temperature resistant waterproof insulation crust 1 mounted on surface has mode selector switch and pattern indication LED lamp 4.

Preferred circuit module 7 is connected with power input 3 through power switch 2, can be switched on or switched off power supply.

Preferred circuit module 7 is made up of preferred circuit and compensating circuit, and preferred circuit and compensating circuit all guarantee the precision of circuit, good stability, and adopt distributed wiring, further eliminated sample room difference.

Can switch standby mode through mode selector switch 4.Standby mode indication LED lamp is connected with the preferred circuit module, can indicate the holding state of the current operation of sample.Be applicable to the stand-by power consumption proficiency testing of multi-field product.Sample can be simulated multiple holding state pattern, comprises the holding state of products such as electronic product, audio & video equipment, household electrical appliance, office equipment, and the frequency response through the switching standards circuit module realizes.

The laboratory records the electric energy of sample at a period of time internal consumption through rational mode of connection, calculates the stand-by power consumption of sample again through average power method formula.

The utility model is through the preferred circuit module of customization; Simulate the holding state of electric detection range product, make the stand-by power consumption power of test checking of sample in the electrical field have versatility: branch fields such as family expenses and similar applications electrical equipment, audio frequency and video and similar electronic equipment, Information Technology Equipment, electric accessories.

Control through the original paper that comprises high temperature resistant waterproof insulation crust, preferred circuit module, binding post and switch in the sample being carried out strictness, thereby satisfy standard for the requirement of homogeneity with stability.
