Abstract
Description
Technical Field
[0001] This application relates to the field of high-voltage contact box equipment technology, and in particular to a high-voltage contact box equipment and its manufacturing method. Background Technology
[0002] The contact box is a crucial component of a power distribution switchgear, used to install stationary contacts. It typically includes a box body, usually located in the busbar compartment on one side of the partition, and installed on the partition within the switchgear cabinet. The box body connects to the truck compartment. The stationary contacts are fixed within the box body to connect or disconnect with the stud contacts of the circuit breaker in the truck compartment. In high-voltage switchgear, the contact box primarily serves as insulation and a transitional connection, playing a vital role in the electrical performance and mechanical stability of the switchgear.
[0003] During the use of high-voltage switchgear, contact boxes often age due to various physical and chemical factors. Firstly, high-voltage switchgear is electrical equipment filled with a large amount of electricity. Partial discharge easily generates ozone, a highly oxidizing substance that readily oxidizes and degrades insulating materials—this is electrical aging. Secondly, besides electrical aging, there is also thermal aging. During operation, high-voltage switchgear easily generates significant heat, causing thermal degradation of polymer insulating materials and the generation or release of low-molecular-weight substances—this is common thermal aging. Thermal aging significantly reduces the insulation and mechanical properties of insulating materials, thus lowering the insulation of the contact box and consequently affecting the overall safe and stable operation of the power system. Summary of the Invention

[0083] It is understood that in the above embodiments, by setting the casting material casting amount matrix and the contact box weight matrix, the casting material casting amount is dynamically adjusted according to the contact box weight, so as to save costs as much as possible while ensuring the stability of the epoxy resin base.
[0084] In a preferred embodiment of this application, when adjusting the amount of casting material according to the spacing between adjacent contact boxes, the following steps are included:
[0085] If there are contact boxes on both sides of the target contact box, obtain the distance between the target contact box and the two side contact boxes and generate an average value, and set the average value as the contact box distance e;
[0086] If there is a contact box on one side of the target contact box, obtain the contact box distance e between the target contact box and the contact box on one side;
[0087] Based on the contact box spacing e, set the pouring volume correction coefficient n, and correct the pouring volume d of the pouring material.
[0088] Specifically, when setting the pouring volume correction factor n based on the contact box spacing e, it includes:
[0089] The preset contact box spacing matrix E is set as E(E1, E2, E3, E4), where E1 is the preset first contact box spacing, E2 is the preset second contact box spacing, E3 is the preset third contact box spacing, and E4 is the preset fourth contact box spacing, and E1 < E2 < E3 < E4.

[0095] If e > E4, the amount of pouring material is not adjusted.
[0096] It is understood that in the above embodiments, by obtaining the contact box spacing, setting a correction coefficient to correct the real-time pouring amount of the pouring material, and adjusting the pouring amount to adjust the size of the epoxy resin base, a reasonable gap is ensured between adjacent contact boxes, avoiding interference between contact boxes, and improving safety assurance for the stable normal operation of the power system.
[0097] In a preferred embodiment of this application, setting the pouring parameters based on the pouring volume of the pouring material includes:
[0098] The real-time pouring speed v is set according to the pouring volume d of the pouring material;
[0099] Obtain real-time ambient temperature data, set the pouring speed compensation coefficient m based on the ambient temperature t, and correct the real-time pouring speed v based on the pouring speed compensation coefficient m.
[0100] Specifically, when setting the real-time pouring speed v based on the pouring volume d of the pouring material, it includes:
[0101] A preset pouring speed matrix V is defined as V(V1, V2, V3, V4), where V1 is the preset first pouring speed, V2 is the preset second pouring speed, V3 is the preset third pouring speed, and V4 is the preset fourth pouring speed, and V1 < V2 < V3 < V4.
[0102] If D1 < d < D2, set the real-time pouring speed v to the preset first pouring speed V1, i.e., v = V1;
[0103] If D2 < d < D3, set the real-time pouring speed v to the preset second pouring speed V2, i.e., v = V2;
[0104] If D3 < d < D4, set the real-time pouring speed v to the preset third pouring speed V3, i.e., v = V3;
[0105] If d > D4, set the real-time pouring speed v to the preset fourth pouring speed V4, i.e., v = V4.
[0106] Specifically, when setting the pouring speed compensation coefficient m based on the ambient temperature t, it includes:
[0107] A preset ambient temperature matrix T is defined as T(T1, T2, T3, T4), where T1 is the preset first ambient temperature, T2 is the preset second ambient temperature, T3 is the preset third ambient temperature, and T4 is the preset fourth ambient temperature, and T1 < T2 < T3 < T4.
[0108] A preset pouring speed compensation coefficient matrix M is defined as M(m1, m2, m3, m4), where m1 is the preset first pouring speed compensation coefficient; m2 is the preset second pouring speed compensation coefficient; m3 is the preset third pouring speed compensation coefficient; m4 is the preset fourth pouring speed compensation coefficient; and 0.8 < m1 < m2 < 1 < m3 < m4 < 1.2.
[0109] If t < T1, set the pouring speed compensation system m = m1, and the corrected real-time pouring speed v = m1 * Vi;
[0110] If T1 < t < T2, set the pouring speed compensation coefficient m = m2, and the corrected real-time pouring speed v = m2 * Vi;

[0113] If t > T4, set the pouring speed compensation system m = m4, and the corrected real-time pouring speed v = m4 * Vi.
[0114] Specifically, by setting a pouring speed matrix, different pouring speeds are set according to different pouring volumes to prevent epoxy resin from failing to form properly or flowing outside the insulating mold during pouring. Simultaneously, a compensation coefficient is set by acquiring real-time ambient temperature to correct the real-time pouring speed, preventing partial solidification of the pouring material during pouring. Furthermore, after pouring, any epoxy resin remaining on the outside of the mold and in the contact box is promptly cleaned to prevent it from hardening and becoming difficult to remove.
[0115] It is understood that in the above embodiments, by obtaining the weight of the contact box to set the amount of casting material to be poured, and dynamically adjusting the pouring time, the strong adhesive force of epoxy resin is used to bond the contact box and epoxy resin into a whole, thereby increasing the contact box's corrosion resistance, heat resistance, acid and alkali resistance, organic solvent resistance and insulation strength.
[0116] In a preferred embodiment of this application, when setting the insulating mold parameters based on the contact box parameters and the cabinet, the following steps are included:
[0117] Obtain the height of the contact box and the cabinet height, generate a height difference 'a' based on the cabinet height and the contact box height, and set the height 'b' of the insulating mold based on the height difference 'a'.

[0120] A preset insulating mold height matrix B is defined as B(B1, B2, B3, B4), where B1 is the preset first insulating mold height, B2 is the preset second insulating mold height, B3 is the preset third insulating mold height, and B4 is the preset fourth insulating mold height, and B1 < B2 < B3 < B4.
[0121] If A1 < a < A2, set the height b of the insulating mold to the preset first insulating mold height B1, that is, b = B1;
[0122] If A2 < a < A3, set the height b of the insulating mold to the preset second insulating mold height B2, that is, b = B2;
[0123] If A3 < a < A4, set the height b of the insulating mold to the preset height B3 of the third insulating mold, that is, b = B3;
[0124] If a > A4, set the height b of the insulating mold to the preset fourth insulating mold height B4, that is, b = B4.
[0125] Specifically, by obtaining the height difference between the contact box and the cabinet, the height of the insulating mold is set, thereby controlling the height of the epoxy resin base and ensuring the compatibility of the epoxy resin base.
[0126] It is understandable that in the above embodiments, by measuring the height of the contact box support and the cabinet and combining the weight of the contact box itself, the parameters of the insulating mold are set to ensure the compatibility of the insulating mold. The insulating mold is made using the insulating plate to prevent the epoxy resin from not forming during the casting process.

[0128] The enclosure includes the busbar outlet, stationary contact mounting insert, and busbar limiting insert.
[0129] The epoxy resin base is connected to the box body and is used to support the box body.
[0130] Specifically, the strong adhesive force of epoxy resin is used to bond the contact box and epoxy resin into a whole.
[0131] Specifically, the largest surface of the epoxy resin casting is in complete contact with the contact box, which increases the insulation between the high-voltage contact box and the cabinet, increases the mechanical strength to support the contact box, and improves the insulation of the high-voltage contact box.
[0132] According to the first concept of this application, the insulation of the high-voltage contact box is improved by replacing the original metal bracket with epoxy resin, which has better insulation and mechanical strength. This solves the problem of reduced insulation of the high-voltage contact box during electrical preventive testing, enhances safety assurance for the stable operation of the power system, and reduces rework procedures and maintenance costs.
[0133] According to the second concept of this application, by measuring the height of the contact box support and the cabinet and combining it with the weight of the contact box itself, the parameters of the insulating mold are set to ensure the compatibility of the insulating mold. The insulating mold is made using an insulating plate to prevent the epoxy resin from not forming during the casting process.
[0134] According to the third concept of this application, the amount of casting material to be poured is set by obtaining the weight of the contact box, and the pouring time is dynamically adjusted. Utilizing the strong adhesive force of epoxy resin, the contact box and epoxy resin are bonded together as a whole, thereby increasing the contact box's corrosion resistance, heat resistance, acid and alkali resistance, organic solvent resistance, and insulation strength.
[0135] The above description is only a preferred embodiment of this application.
