Abstract
The utility model relates to a photovoltaic assembly heat cycle test overtemperature protection device. The device comprises an energization control cabinet. The energization control cabinet is equipped with a zero line circuit and a live wire circuit, which are respectively connected with a zero line and a live wire. A manual switch SB1 is arranged in the zero line circuit at a position close to the zero line N, and a normally-closed switch KM1 is arranged in the zero line circuit at a position close to the energization control cabinet. The normally-closed switch KM1 is sequentially connected in parallel with a contactor KM, a relay KA, and a digital temperature controller U1. The contactor KM is connected in series with a normally-opened switch KA1. The relay KA is connected in series with a temperature control switch U1temp. When the photovoltaic assembly heat cycle test overtemperature protection device is used in a photovoltaic assembly heat cycle test, a monitoring system can stop energizing once a photovoltaic assembly has a fault in a high temperature phase environment test box, so that the assembly is prevented from overheating, a backboard junction box and other parts is prevented from losing efficacy, and the safety of the test is improved.
Description
Technical field
The utility model relates to a kind of photovoltaic module test field, relates in particular to a kind of photovoltaic module thermal cycling test overtemperature protection device.
Background technology
In the photovoltaic module thermal cycling test, during greater than 25 ℃, need apply maximum power point electric current (generally between 5～10A) in temperature to photovoltaic module according to IEC61215.After but the hot stage environmental test chamber broke down, supervisory system can continue energising, causes assembly overheated, and then caused failure effect such as backboard terminal box test process and security, and product is caused damage, had increased cost.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of photovoltaic module after the hot stage environmental test chamber breaks down, and supervisory system no longer continues energising, thereby can not cause the overheated photovoltaic module thermal cycling test overtemperature protection device of assembly.
In order to solve the problems of the technologies described above; the utility model is achieved through the following technical solutions: a kind of photovoltaic module thermal cycling test overtemperature protection device; comprise the energising switch board; described energising switch board is provided with respectively zero line circuit and the live wire circuit that is connected with live wire with zero line; described zero line circuit is provided with hand switch SB1 by the position of zero line N; position by the energising switch board is provided with normally closed switch KM1; on the described normally closed switch KM1 successively and be connected to contactor KM; relay K A and digital temperature control U1; be serially connected with normal open switch KA1 on the described contactor KM, be serially connected with temperature detect switch (TDS) U1temp on the relay K A.
Compared with prior art; usefulness of the present utility model is: this photovoltaic module thermal cycling test overtemperature protection device is in the photovoltaic module thermal cycling test; in case photovoltaic module is after the hot stage environmental test chamber breaks down; supervisory system no longer continues energising; thereby can not cause assembly overheated; backboard terminal box etc. can not be lost efficacy, improve the security of test.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model photovoltaic module thermal cycling test overtemperature protection device circuit diagram.
Among the figure: 1, energising switch board; 2, zero line circuit; 3, live wire circuit.
Embodiment:
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
A kind of photovoltaic module thermal cycling test overtemperature protection device shown in Figure 1 comprises energising switch board 1, and described energising switch board 1 is the inner energising of photovoltaic module TC200 test switch board; Described energising switch board 1 is provided with respectively zero line circuit 2 and the live wire circuit 3 that is connected with live wire L with zero line N, described zero line circuit 2 is provided with hand switch SB1 by the position of zero line N, position by energising switch board 1 is provided with normally closed switch KM1, on the described normally closed switch KM1 successively and be connected to contactor KM, relay K A and digital temperature control U1, be serially connected with normal open switch KA1 on the described contactor KM, be serially connected with temperature detect switch (TDS) U1temp on the relay K A.
Its concrete operations mode is as follows, and in actual use, it is T1 that the highest limit temperature is set, when temperature is lower than T1, digital temperature control U1 no-output, temperature detect switch (TDS) U1temp often leaves, normal open switch KA1 on the relay K A often opens, and normally closed switch KM1 is normally closed, and energising switch board 1 is switched on to assembly; When temperature was higher than T1, digital temperature control U1 exported high level, temperature detect switch (TDS) U1temp closure, and relay K A adhesive, normal open switch KA1 closure, contactor KM adhesive, normally closed switch KM1 disconnects, and energising switch board 1 stops to switch on to assembly.
This installs being applied as in the photovoltaic thermal cycling test: the temperature in the chamber of PT100 induced environment, when temperature exceeds the capping temperature, PT100 can give signal of attemperating unit, and then cuts off the power supply of supervisory system.
This photovoltaic module thermal cycling test overtemperature protection device is in the photovoltaic module thermal cycling test; in case photovoltaic module is after the hot stage environmental test chamber breaks down; supervisory system no longer continues energising; thereby can not cause assembly overheated; backboard terminal box etc. can not be lost efficacy, improve the security of test.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
