Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention is further described:

[0027] Electric performance multi-function tester for heating elements, including seven parts: leakage current test display 1, small current meter display 2, voltmeter 3, temperature controller 4, voltage regulating part 5, contactor 6 and switch operation interface 7;

[0028] The leakage current test display 1 is used to display the leakage current value on the heating element simulation shell; the input end of the leakage current test display 1 is connected with the heating element simulation shell, and the leakage current signal on the heating element simulation shell is processed and displayed come out;

[0029] The small current instrument display 2 is used to display the power, voltage, current and frequency of the electric heating element when the operating voltage at both ends of the electric heating element is 0-250V; the input end of the small current instrument disp...

Abstract

The invention discloses a multifunctional tester for electrical performance of an electrical heating element, belongs to the technical field of power electronics, and aims to solve the problem that the existing multi-functional tester has small power and cannot meet the requirement on testing of the electrical performance of the electrical heating element. The multifunctional tester for the electrical performance of the electrical heating element comprises seven parts of a leakage current test display, a small-current meter display, a voltmeter, a temperature controller, a voltage adjusting part, a contactor and a switch operation interface. The tester is mainly used for thermal state leakage current testing, rated power testing, overload testing and overheating testing of the electrical heating element of a metal shell at rated power and specified temperature, and can be widely used for manufacturing enterprises for producing the electrical heating elements.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a multifunctional tester for electric performance of electric heating elements. Background technique [0002] Since the power of the leakage current testers sold on the market is relatively small, generally between 0.5KVA and 1KVA, the actual power, current, and thermal leakage current of the heating element cannot be optimally detected, let alone damaged. The electrical parameters of the electric heating element under the permanent test cannot meet the actual production needs of the enterprise. Contents of the invention [0003] The invention discloses a multifunctional tester for the electrical performance of an electric heating element, which is used to solve the problem that the existing multifunctional tester has relatively low power and cannot meet the electrical performance test of the electric heating element. [0004] The present invention is ach...
