Embodiment 1

[0031] A wire pull-out proof electrical cabinet with a protective layer such as figure 1 As shown, it includes an electrical cabinet body 3 with a cable inlet 1 and a cable outlet 2, and an insulating protective layer 9 is also provided on the inner wall of the electrical cabinet body 3, and the cable inlet 1 and the cable outlet in the electrical cabinet body 3 Anti-pull pieces 4 are provided at the positions of the cable outlets 2 .

[0032] Such as figure 2 As shown, the anti-pull member 4 includes a baffle plate 41 fixed on the electrical cabinet body 3 and having a cable through hole, a fixing plate 42 having a cable through hole and fixing the cable in the cable through hole, And the spring 43 whose two ends are respectively connected to the baffle plate 41 and the fixed plate 42;

[0033] In this embodiment, the insulating protective layer is composed of the following components by weight:

[0034] 23 parts by weight of ethylene vinyl acetate; 18 parts by weight of ...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that this embodiment optimizes the detachable partition 6, and the specific structure is set as follows:

[0044] Both the cable inlet 1 and the cable outlet 2 are located at the bottom of the electrical cabinet body 3, and a protruding block 5 is arranged on the electrical cabinet body 3 above the anti-pull member 4, and a detachable partition is placed on the protruding block 5. board6.

[0045] Such as image 3 As shown, the detachable partition 6 consists of a plate body 61 and is arranged on a through groove 62 with one end open on the plate body 61 .

[0046] At the same time, the electrical cabinet body 3 is also provided with an air vent 7 .

Embodiment 3

[0048] The difference between this embodiment and Embodiment 1 is that the content of each component of the insulating protective layer is different in this embodiment, and the specific components are set as follows:

[0049] 115 parts by weight of methyl vinyl silicone rubber; 25 parts by weight of ethylene vinyl acetate; 12 parts by weight of cycloaliphatic epoxy resin; 16 parts by weight of m-xylylenediamine; 16 parts by weight of fumed silica; 5 parts by weight of tetrahydrofuran; 0.9 parts by weight of aluminum oxide; 0.6 parts by weight of benzoyl peroxide; 2.6 parts by weight of polybutanoximinosilane; 1.8 parts by weight of hydrogen-containing silicone oil.

[0050] In this embodiment, the bonding strength between the insulating protective layer and the electrical cabinet body is 109 Mpa. The temperature resistance of the insulating protective layer in this embodiment reaches above 120°C. In the present embodiment, the conductivity of the insulating protective layer i...

Abstract

The invention discloses a line pulling-out preventing type electrical cabinet with a protective layer. The line pulling-out preventing type electrical cabinet mainly settles a problem of insufficient connection stability of a cable at connection portions in the electrical cabinet in cable wiring operation in prior art. The electrical cabinet comprises an electrical cabinet body which is provided with a cable inlet and a cable outlet. The inner wall of the electrical cabinet body is provided with an insulating protecting layer. The cable inlet and the cable outlet in the electrical cabinet body are respectively provided with an anti-pulling member. The anti-pulling member comprises a baffle plate which is fixed on the electrical cabinet body and is provided with a cable through hole, a fixing plate which is provided with a cable through hole and fixes the cable in the cable through hole; and a spring of which the two ends are respectively connected with the baffle plate and the fixing plate. A center connecting line between the cable through hole of the baffle plate and the cable through hole of the fixing plate and the central axis of the spring are in one straight line. The line pulling-out preventing type electrical cabinet has advantages of high connection stability, effective prevention for an influence at a connecting portion in wiring operation, etc.

Description

technical field [0001] The invention relates to an electric cabinet, in particular to a circuit pull-out prevention type electric cabinet with a protective layer. Background technique [0002] The electrical cabinet is a kind of electrical equipment. The main function of the electrical cabinet is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the electrical cabinet are mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers and various protective devices. There are many classification methods for electrical cabinets. For example, according to the installation method of circuit breakers, they can be divided into removable electrical cabinets and fixed electrical cabinets; or according to the different cabinet structures, they can be divided into open electrical cabinets, metal enclosed el...
